         *  - size: the size of the group. Alternatively the width and height properties 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 rectangle).
         *  - 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.
         *  - 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.
         *  - borderThickness: the thickness of the drawn border, default is 1.
         *  - isVisible: true if the primitive must be visible, false for hidden. Default is true.
         *  - marginTop/Left/Right/Bottom: define the margin for the corresponding edge, if all of them are null, margin is not used in layout computing. Default Value is null for each.
         *  - hAlighment: define horizontal alignment of the Canvas, alignment is optional, default value null: no alignment.
