Large patch:
- FX bug fixes. - Polygon mode and edgeflag work properly. - Clipping works with edgeflag. - Driver.ReducedPrimitiveChange() callback so drivers that implement lines & points as triangles can turn culling off before rendering groups of these primitives. - Cleaned up feedback & select primitives.
