         * - 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)
