Does basically the same as "cirrus: stop passing around dst pointers in
976a86
the blitter", just for the src pointer instead of the dst pointer.
976a86
976a86
For the src we have to care about cputovideo blits though and fetch the
976a86
data from s->cirrus_bltbuf instead of vga memory.  The cirrus_src*()
976a86
helper functions handle that.
