- ok, fancy coppertricks won't work, but vports and playfileds could be
- done by planar-to-chunky conversion.
-
- some gfx-cards are said to have this in hardware.
-
- not impossible for the gfx-card hardware, but needs clever software, and
- fancy AGA fx might run slower on gfx-card than on vanilla A1200 :->
-
- well, I'm still wrestling with an OS fan to get out if there is a
- way for using OS routines (attached vports) for such things.
-
- if so, and if the gfx-card drivers also support this os routines,
- things could even get quite easy to program...
-
- but problemo, how to get a bitmap in _fastmem_ p2ced via OS ?
- blitbitmaprastport will need a chipmem bitmap :\
