- I did not know if there were some exotic ones doing this, so
- I was careful ;)
-
- p2c is needed for fast planar bitmap dump while c2p is a
- quite luxurious thing that will speed up conversions
- from chunky-bitmaps to planar ones, only needed if you
- read bitmaps from gfx-card-screen into native bitmaps, which
- is IMHO done by far less software than the other way around.
-
- anyway the c2p chip is no use for doom, so.... ;)
