Copperbox revision 2603.

Work deprecating Basic.Geometry and cleaning up Drawing.Basis.DrawingPrimitives.

Basic.Geometry doesn't merit its place in Basic as it is only adding code which is used by Shapes in Drawing. As Shapes are quite difficult to implement, Basic.Geometry will probably stick around for a while but at least I'll know not to use it...

Drawing.Basis.DrawingPrimitives is adding quite a few drawing functions that aren't really merited - minor short-hands for functions that exist elsewhere. They are likely to be better off in a more expansive short-hand module that can also provide short-hands for the shapes (for example) and so won't be particularly primitive.
