         *  - 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]

         *  - scale: the initial scale of the primitive. default is 1
         *  - 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)

         * - 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
