- You mean like D = A and B ? Afaik not possible. You must specify miniterms
- in routines like blitbitmaprastport(), but then A will point to a mask and
- not to the data you want.
- I also don't know if other miniterms than "copy" will be interpreted
- correct on gfx-cards, who knows...
-
- do this:
-
- ownblitter() waitblit() "do blitter hardware stuff" disownblitter()
-
- if someone could add the test for presence of a chipset blitter ;)
-
- I would have liked a os function like
-
- blitter(A,B,C,D,mask,... );
-
- with the routine beeing emulation on fastmem, draco, whatever...
