     * The only flaw of SDF is that the rendering quality may not be the best or the edges too sharp is the font thickness is too thin.

         * Create an Logical or Renderable Group.
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y properties can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - trackNode: if you want the ScreenSpaceCanvas to track the position of a given Scene Node, use this setting to specify the Node to track
         * - trackNodeOffset: if you use trackNode you may want to specify a 3D Offset to apply to shift the Canvas
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - size: the size of the group. Alternatively the width and height properties can be set. If null the size will be computed from its content, default is null.
         *  - cacheBehavior: Define how the group should behave regarding the Canvas's cache strategy, default is Group2D.GROUPCACHEBEHAVIOR_FOLLOWCACHESTRATEGY
         * - layoutEngine: either an instance of a layout engine based class (StackPanel.Vertical, StackPanel.Horizontal) or a string ('canvas' for Canvas layout, 'StackPanel' or 'HorizontalStackPanel' for horizontal Stack Panel layout, 'VerticalStackPanel' for vertical Stack Panel layout).
         * - isVisible: true if the group must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginBottom: bottom margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - margin: top, left, right and bottom margin formatted as a single string (see PrimitiveThickness.fromString)
         * - marginHAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginVAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginAlignment: a string defining the alignment, see PrimitiveAlignment.fromString
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingRight: right padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)

         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - size: the size of the sprite displayed in the canvas, if not specified the spriteSize will be used
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property

         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - alignToPixel: the rendered lines will be aligned to the rendering device' pixels
         * - isVisible: true if the sprite must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)

         * Create an Rectangle 2D Shape primitive. May be a sharp rectangle (with sharp corners), or a rounded one.
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y settings can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - size: the size of the group. Alternatively the width and height settings can be set. Default will be [10;10].
         * - roundRadius: if the rectangle has rounded corner, set their radius, default is 0 (to get a sharp edges rectangle).
         * - fill: the brush used to draw the fill content of the rectangle, you can set null to draw nothing (but you will have to set a border brush), default is a SolidColorBrush of plain white. can also be a string value (see Canvas2D.GetBrushFromString)
         * - border: the brush used to draw the border of the rectangle, you can set null to draw nothing (but you will have to set a fill brush), default is null. can also be a string value (see Canvas2D.GetBrushFromString)
         * - borderThickness: the thickness of the drawn border, default is 1.
         * - isVisible: true if the primitive must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).

         * Create an Ellipse 2D Shape primitive
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id: a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y properties can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - size: the size of the group. Alternatively the width and height properties can be set. Default will be [10;10].
         * - subdivision: the number of subdivision to create the ellipse perimeter, default is 64.
         * - fill: the brush used to draw the fill content of the ellipse, you can set null to draw nothing (but you will have to set a border brush), default is a SolidColorBrush of plain white. can also be a string value (see Canvas2D.GetBrushFromString)
         * - border: the brush used to draw the border of the ellipse, you can set null to draw nothing (but you will have to set a fill brush), default is null. can be a string value (see Canvas2D.GetBrushFromString)
         * - borderThickness: the thickness of the drawn border, default is 1.
         * - isVisible: true if the group must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginBottom: bottom margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - margin: top, left, right and bottom margin formatted as a single string (see PrimitiveThickness.fromString)
         * - marginHAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginVAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginAlignment: a string defining the alignment, see PrimitiveAlignment.fromString
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)

         * Create an 2D Sprite primitive
         * @param texture the texture that stores the sprite to render
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y properties can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - size: the size of the sprite displayed in the canvas, if not specified the spriteSize will be used
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - spriteSize: the size of the sprite (in pixels) as it is stored in the texture, if null the size of the given texture will be used, default is null.
         * - spriteLocation: the location (in pixels) in the texture of the top/left corner of the Sprite to display, default is null (0,0)
         * - spriteScaleFactor: DEPRECATED. Old behavior: say you want to display a sprite twice as big as its bitmap which is 64,64, you set the spriteSize to 128,128 and have to set the spriteScaleFactory to 0.5,0.5 in order to address only the 64,64 pixels of the bitmaps. Default is 1,1.
         * - scale9: draw the sprite as a Scale9 sprite, see http://yannickloriot.com/2013/03/9-patch-technique-in-cocos2d/ for more info. x, y, w, z are left, bottom, right, top coordinate of the resizable box
         * - invertY: if true the texture Y will be inverted, default is false.
         * - alignToPixel: if true the sprite's texels will be aligned to the rendering viewport pixels, ensuring the best rendering quality but slow animations won't be done as smooth as if you set false. If false a texel could lies between two pixels, being blended by the texture sampling mode you choose, the rendering result won't be as good, but very slow animation will be overall better looking. Default is true: content will be aligned.
         * - isVisible: true if the sprite must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginBottom: bottom margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - margin: top, left, right and bottom margin formatted as a single string (see PrimitiveThickness.fromString)
         * - marginHAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginVAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginAlignment: a string defining the alignment, see PrimitiveAlignment.fromString
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingRight: right padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingBottom: bottom padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)

         * @param text the text to display
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y properties can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - fontName: the name/size/style of the font to use, following the CSS notation. Default is "12pt Arial".
         * - fontSuperSample: if true the text will be rendered with a superSampled font (the font is twice the given size). Use this settings if the text lies in world space or if it's scaled in.
         * - signedDistanceField: if true the text will be rendered using the SignedDistanceField technique. This technique has the advantage to be rendered order independent (then much less drawing calls), but only works on font that are a little more than one pixel wide on the screen but the rendering quality is excellent whatever the font size is on the screen (which is the purpose of this technique). Outlining/Shadow is not supported right now. If you can, you should use this mode, the quality and the performances are the best. Note that fontSuperSample has no effect when this mode is on.
         * - defaultFontColor: the color by default to apply on each letter of the text to display, default is plain white.
         * - areaSize: the size of the area in which to display the text, default is auto-fit from text content.
         * - tabulationSize: number of space character to insert when a tabulation is encountered, default is 4
         * - isVisible: true if the text must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginBottom: bottom margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - margin: top, left, right and bottom margin formatted as a single string (see PrimitiveThickness.fromString)
         * - marginHAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginVAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginAlignment: a string defining the alignment, see PrimitiveAlignment.fromString

         * Create an 2D Lines Shape primitive. The defined lines may be opened or closed (see below)
         * @param points an array that describe the points to use to draw the line, must contain at least two entries.
         * @param settings a combination of settings, possible ones are
         * - parent: the parent primitive/canvas, must be specified if the primitive is not constructed as a child of another one (i.e. as part of the children array setting)
         * - children: an array of direct children
         * - id a text identifier, for information purpose
         * - position: the X & Y positions relative to its parent. Alternatively the x and y properties can be set. Default is [0;0]
         * - rotation: the initial rotation (in radian) of the primitive. default is 0
         * - scale: the initial scale of the primitive. default is 1. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - fillThickness: the thickness of the fill part of the line, can be null to draw nothing (but a border brush must be given), default is 1.
         * - closed: if false the lines are said to be opened, the first point and the latest DON'T connect. if true the lines are said to be closed, the first and last point will be connected by a line. For instance you can define the 4 points of a rectangle, if you set closed to true a 4 edges rectangle will be drawn. If you set false, only three edges will be drawn, the edge formed by the first and last point won't exist. Default is false.
         * - startCap: Draw a cap of the given type at the start of the first line, you can't define a Cap if the Lines2D is closed. Default is Lines2D.NoCap.
         * - endCap: Draw a cap of the given type at the end of the last line, you can't define a Cap if the Lines2D is closed. Default is Lines2D.NoCap.
         * - fill: the brush used to draw the fill content of the lines, you can set null to draw nothing (but you will have to set a border brush), default is a SolidColorBrush of plain white. can be a string value (see Canvas2D.GetBrushFromString)
         * - border: the brush used to draw the border of the lines, you can set null to draw nothing (but you will have to set a fill brush), default is null. can be a string value (see Canvas2D.GetBrushFromString)
         * - borderThickness: the thickness of the drawn border, default is 1.
         * - isVisible: true if the primitive must be visible, false for hidden. Default is true.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value is true.
         * - childrenFlatZOrder: if true all the children (direct and indirect) will share the same Z-Order. Use this when there's a lot of children which don't overlap. The drawing order IS NOT GUARANTED!
         * - levelCollision: this primitive is an actor of the Collision Manager and only this level will be used for collision (i.e. not the children). Use deepCollision if you want collision detection on the primitives and its children.
         * - deepCollision: this primitive is an actor of the Collision Manager, this level AND ALSO its children will be used for collision (note: you don't need to set the children as level/deepCollision).
         * - layoutData: a instance of a class implementing the ILayoutData interface that contain data to pass to the primitive parent's layout engine
         * - marginTop: top margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginLeft: left margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginRight: right margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - marginBottom: bottom margin, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - margin: top, left, right and bottom margin formatted as a single string (see PrimitiveThickness.fromString)
         * - marginHAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginVAlignment: one value of the PrimitiveAlignment type's static properties
         * - marginAlignment: a string defining the alignment, see PrimitiveAlignment.fromString
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingRight: right padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingBottom: bottom padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - padding: top, left, right and bottom padding formatted as a single string (see PrimitiveThickness.fromString)

         * - children: an array of direct children primitives
         * - id: a text identifier, for information purpose only, default is null.
         * - unitScaleFactor: if specified the created canvas will be with a width of size.width*unitScaleFactor and a height of size.height.unitScaleFactor. If not specified, the unit of 1 is used. You can use this setting when you're dealing with a 3D world with small coordinates and you need a Canvas having bigger coordinates (typically to display text with better quality).
         * - worldPosition the position of the Canvas in World Space, default is [0,0,0]
         * - worldRotation the rotation of the Canvas in World Space, default is Quaternion.Identity()
         * - trackNode: if you want the WorldSpaceCanvas to track the position/rotation/scale of a given Scene Node, use this setting to specify the Node to track
         * - trackNodeOffset: if you use trackNode you may want to specify a 3D Offset to apply to shift the Canvas
         * - trackNodeBillboard: if true the WorldSpaceCanvas will always face the screen
         * - sideOrientation: Unexpected behavior occur if the value is different from Mesh.DEFAULTSIDE right now, so please use this one, which is the default.
         * - cachingStrategy Must be CACHESTRATEGY_CANVAS for now, which is the default.
         * - enableInteraction: if true the pointer events will be listened and rerouted to the appropriate primitives of the Canvas2D through the Prim2DBase.onPointerEventObservable observable property. Default is false (the opposite of ScreenSpace).
         * - isVisible: true if the canvas must be visible, false for hidden. Default is true.
         * - backgroundRoundRadius: the round radius of the background, either backgroundFill or backgroundBorder must be specified.
         * - backgroundFill: the brush to use to create a background fill for the canvas. can be a string value (see Canvas2D.GetBrushFromString) or a IBrush2D instance.
         * - backgroundBorder: the brush to use to create a background border for the canvas. can be a string value (see Canvas2D.GetBrushFromString) or a IBrush2D instance.
         * - backgroundBorderThickness: if a backgroundBorder is specified, its thickness can be set using this property
         * - customWorldSpaceNode: if specified the Canvas will be rendered in this given Node. But it's the responsibility of the caller to set the "worldSpaceToNodeLocal" property to compute the hit of the mouse ray into the node (in world coordinate system) as well as rendering the cached bitmap in the node itself. The properties cachedRect and cachedTexture of Group2D will give you what you need to do that.
         * - maxAdaptiveCanvasSize: set the max size (width and height) of the bitmap that will contain the cached version of the WorldSpace Canvas. Default is 1024 or less if it's not supported. In any case the value you give will be clipped by the maximum that WebGL supports on the running device. You can set any size, more than 1024 if you want, but testing proved it's a good max value for non "retina" like screens.
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingRight: right padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - paddingBottom: bottom padding, can be a number (will be pixels) or a string (see PrimitiveThickness.fromString)
         * - padding: top, left, right and bottom padding formatted as a single string (see PrimitiveThickness.fromString)

         * Create a new 2D ScreenSpace Rendering Canvas, it is a 2D rectangle that has a size (width/height) and a position relative to the bottom/left corner of the screen.
         * ScreenSpace Canvas will be drawn in the Viewport as a 2D Layer lying to the top of the 3D Scene. Typically used for traditional UI.
         * All caching strategies will be available.
         * PLEASE NOTE: the origin of a Screen Space Canvas is set to [0;0] (bottom/left) which is different than the default origin of a Primitive which is centered [0.5;0.5]
         * @param scene the Scene that owns the Canvas
         * @param settings a combination of settings, possible ones are
         *  - children: an array of direct children primitives
         *  - id: a text identifier, for information purpose only
         *  - x: the position along the x axis (horizontal), relative to the left edge of the viewport. you can alternatively use the position setting.
         *  - y: the position along the y axis (vertically), relative to the bottom edge of the viewport. you can alternatively use the position setting.
         *  - position: the position of the canvas, relative from the bottom/left of the scene's viewport. Alternatively you can set the x and y properties directly. Default value is [0, 0]
         *  - width: the width of the Canvas. you can alternatively use the size setting.
         *  - height: the height of the Canvas. you can alternatively use the size setting.
         *  - size: the Size of the canvas. Alternatively the width and height properties can be set. If null two behaviors depend on the cachingStrategy: if it's CACHESTRATEGY_CACHECANVAS then it will always auto-fit the rendering device, in all the other modes it will fit the content of the Canvas
         *  - renderingPhase: you can specify for which camera and which renderGroup this canvas will render to enable interleaving of 3D/2D content through the use of renderinGroup. As a rendering Group is rendered for each camera, you have to specify in the scope of which camera you want the canvas' render to be made. Default behavior will render the Canvas at the very end of the render loop.
         *  - designSize: if you want to set the canvas content based on fixed coordinates whatever the final canvas dimension would be, set this. For instance a designSize of 360*640 will give you the possibility to specify all the children element in this frame. The Canvas' true size will be the HTMLCanvas' size: for instance it could be 720*1280, then a uniform scale of 2 will be applied on the Canvas to keep the absolute coordinates working as expecting. If the ratios of the designSize and the true Canvas size are not the same, then the scale is computed following the designUseHorizAxis member by using either the size of the horizontal axis or the vertical axis.
         *  - designUseHorizAxis: you can set this member if you use designSize to specify which axis is priority to compute the scale when the ratio of the canvas' size is different from the designSize's one.
         *  - cachingStrategy: either CACHESTRATEGY_TOPLEVELGROUPS, CACHESTRATEGY_ALLGROUPS, CACHESTRATEGY_CANVAS, CACHESTRATEGY_DONTCACHE. Please refer to their respective documentation for more information. Default is Canvas2D.CACHESTRATEGY_DONTCACHE
         *  - enableInteraction: if true the pointer events will be listened and rerouted to the appropriate primitives of the Canvas2D through the Prim2DBase.onPointerEventObservable observable property. Default is true.
         *  - isVisible: true if the canvas must be visible, false for hidden. Default is true.
         * - backgroundRoundRadius: the round radius of the background, either backgroundFill or backgroundBorder must be specified.
         * - backgroundFill: the brush to use to create a background fill for the canvas. can be a string value (see BABYLON.Canvas2D.GetBrushFromString) or a IBrush2D instance.
         * - backgroundBorder: the brush to use to create a background border for the canvas. can be a string value (see BABYLON.Canvas2D.GetBrushFromString) or a IBrush2D instance.
         * - backgroundBorderThickness: if a backgroundBorder is specified, its thickness can be set using this property
         * - customWorldSpaceNode: if specified the Canvas will be rendered in this given Node. But it's the responsibility of the caller to set the "worldSpaceToNodeLocal" property to compute the hit of the mouse ray into the node (in world coordinate system) as well as rendering the cached bitmap in the node itself. The properties cachedRect and cachedTexture of Group2D will give you what you need to do that.
         * - paddingTop: top padding, can be a number (will be pixels) or a string (see BABYLON.PrimitiveThickness.fromString)
         * - paddingLeft: left padding, can be a number (will be pixels) or a string (see BABYLON.PrimitiveThickness.fromString)
         * - paddingRight: right padding, can be a number (will be pixels) or a string (see BABYLON.PrimitiveThickness.fromString)
         * - paddingBottom: bottom padding, can be a number (will be pixels) or a string (see BABYLON.PrimitiveThickness.fromString)
         * - padding: top, left, right and bottom padding formatted as a single string (see BABYLON.PrimitiveThickness.fromString)
