Adds *Path functions to dc funcs table + add EnhMetaFile recording.
Separate out Polylne/PolylineTo and PolyBezier/PolyBezierTo in dc
funcs table to enable proper enhmetafile recording.
The current position update in *To functions is now handled by the
main function and not in the drivers.
Move USER functions from graphics/painting.c -> windows/painting.c
