         * - isVisible: true if the canvas must be visible, false for hidden. Default is true.

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.

         * @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
         * - 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)

         * - 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
         * - 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)

         * 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.
