         * 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. You can alternatively use scaleX &| scaleY to apply non uniform scale
         * - dontInheritParentScale: if set the parent's scale won't be taken into consideration to compute the actualScale property
         * - opacity: set the overall opacity of the primitive, 1 to be opaque (default), less than 1 to be transparent.
         * - zOrder: override the zOrder with the specified value
         * - 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.
         * - isPickable: if true the Primitive can be used with interaction mode and will issue Pointer Event. If false it will be ignored for interaction/intersection test. Default value is true.
         * - isContainer: if true the Primitive acts as a container for interaction, if the primitive is not pickable or doesn't intersection, no further test will be perform on its children. If set to false, children will always be considered for intersection/interaction. Default value 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)
