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
