Added three simple tooling Primitives: (1) SingleLinePrimitive2D: Just a Line from Point A to B with a BColor, decomposes to a PolygonHairlinePrimitive2D (and to a PointArrayPrimitive2D if only a single point aka A == B) (2) LineRectanglePrimitive2D: (3) FilledRectanglePrimitive2D: Rectangles that support fill or line, gets decomposed to maybe PolyPolygonColorPrimitive2D (if filled) and a PolygonHairlinePrimitive2D (if line) or nothing if the B2DRange is empty NOTE: If using these despite being hor/ver aligned due to their nature as B2DRange(s) (aka 'non rotated/sheared') these may have to be transformed if the current transformation context you are working in is rotated or sheared, so *ensure* to handle these correctly if you do handle them yourself. This is not needed with the Polygon-based ones - that's why these are - and stay - the common case(s). Both are hairline primitives themselves, so are potentially *view-dependent* (see comment in *.cxx and *.hxx). They will be useful as very simple primitives for small renderers, e.g. to avoid conversion from rectangles or just lines to polygons. The more general Primitives are always the polygon-based ones, so these new ones get decomposed to these (decomposition direction, complex -> simpler). This assures that a processor/renderer has minimally to support the polygon-based ones, but *can* use these simple tooling ones directly if he wants to. This will come in handy for future System-Dependent PrimitiveRenderers, which I am currently working on one to offer as example - this leads to identifying helpful upstream things that will come in handy in that regard - like these ones.
