add HP98550 high-res color graphic card
Used in the high end HP9000/300 machines. Provides a resolution of 1280x1024 @ 8bpp. It also provides two overlay planes and one phantom plane. Each plane contains two window movers that are used for copying characters and tiles on the screen. It also has a RUG for line/vector drawing. The current state implements everything that is required to have a working HP Visual user environment in MAME. Working: - window mover - pixel replacement rules - window replacement rules - f0 tripple replacement rule (copy src or keep destination depending on pattern register) - VRAM bit access mode - solid line drawing Not implemented yet: - drawing circles - linetype vector/circles - rectangles - filling areas - tripple replacement rules other than f0
