         * The parameter `height` sets the height size (float) of the cylinder/cone (float, default 2).
         * The parameter `diameter` sets the diameter of the top and bottom cap at once (float, default 1).
         * The parameters `diameterTop` and `diameterBottom` overwrite the parameter `diameter` and set respectively the top cap and bottom cap diameter (floats, default 1). The parameter "diameterBottom" can't be zero.
         * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.
         * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
         * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.
         * The parameter `enclose`  (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.
         * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.
         * You can set different colors and different images to each box side by using the parameters `faceColors` (an array of n Color3 elements) and `faceUV` (an array of n Vector4 elements).
         * The value of n is the number of cylinder faces. If the cylinder has only 1 subdivisions, n equals : top face + cylinder surface + bottom face = 3
         * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
         * Finally, if the cylinder has 5 independent subdivisions and is enclose, n equals : top face + 5 x (stripe surface + 2 closing faces) + bottom face = 2 + 5 * 3 = 17
         * Each array (color or UVs) is always ordered the same way : the first element is the bottom cap, the last element is the top cap. The other elements are each a ring surface.
         * If `enclose` is false, a ring surface is one element.
         * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.

         *
         * tuto : http://doc.babylonjs.com/tutorials/Mesh_CreateXXX_Methods_With_Options_Parameter#polyhedron
         * The parameter `type` (positive integer, max 14, default 0) sets the polyhedron type to build among the 15 embbeded types. Please refer to the type sheet in the tutorial
         *  to choose the wanted type.
         * The parameter `size` (positive float, default 1) sets the polygon size.
         * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value).
         * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overwrittes the parameter `type`.
         * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron
         * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`).
         * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : http://doc.babylonjs.com/tutorials/CreateBox_Per_Face_Textures_And_Colors
         * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored.
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation
         * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.

         * - 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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - 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.
         * - 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!
         * - 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)

         * 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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - 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.
         * - 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!
         * - 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)

         * 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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - 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.
         * - 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!
         * - 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)

         * 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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - origin: define the normalized origin point location, default [0.5;0.5]
         * - spriteSize: the size of the sprite (in pixels), 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)
         * - 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.
         * - 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!
         * - 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)

         * Create a Text primitive
         * @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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - 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.
         * - defaultColor: 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.
         * - 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!
         * - 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)

         * 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
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - 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.
         * - 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!
         * - 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)

            Mapping Texture Coordinates to Cube Map Faces
            Because there are multiple faces, the mapping of texture coordinates to positions on cube map faces
            is more complicated than the other texturing targets.  The EXT_texture_cube_map extension is purposefully
            designed to be consistent with DirectX 7's cube map arrangement.  This is also consistent with the cube
            map arrangement in Pixar's RenderMan package.
            For cube map texturing, the (s,t,r) texture coordinates are treated as a direction vector (rx,ry,rz)
            emanating from the center of a cube.  (The q coordinate can be ignored since it merely scales the vector
            without affecting the direction.) At texture application time, the interpolated per-fragment (s,t,r)
            selects one of the cube map face's 2D mipmap sets based on the largest magnitude coordinate direction
            the major axis direction). The target column in the table below explains how the major axis direction
            maps to the 2D image of a particular cube map target.
    
            major axis
            direction     target                              sc     tc    ma
            ----------    ---------------------------------   ---    ---   ---
            +rx          GL_TEXTURE_CUBE_MAP_POSITIVE_X_EXT   -rz    -ry   rx
            -rx          GL_TEXTURE_CUBE_MAP_NEGATIVE_X_EXT   +rz    -ry   rx
            +ry          GL_TEXTURE_CUBE_MAP_POSITIVE_Y_EXT   +rx    +rz   ry
            -ry          GL_TEXTURE_CUBE_MAP_NEGATIVE_Y_EXT   +rx    -rz   ry
            +rz          GL_TEXTURE_CUBE_MAP_POSITIVE_Z_EXT   +rx    -ry   rz
            -rz          GL_TEXTURE_CUBE_MAP_NEGATIVE_Z_EXT   -rx    -ry   rz
    
            Using the sc, tc, and ma determined by the major axis direction as specified in the table above,
            an updated (s,t) is calculated as follows
            s   =   ( sc/|ma| + 1 ) / 2
            t   =   ( tc/|ma| + 1 ) / 2
            If |ma| is zero or very nearly zero, the results of the above two equations need not be defined
            (though the result may not lead to GL interruption or termination).  Once the cube map face's 2D mipmap
            set and (s,t) is determined, texture fetching and filtering proceeds like standard OpenGL 2D texturing.
