/* copy src -> dst except for transparent color in src*/
#define MWROP_SRCTRANSCOPY 0x01000000L
Just what we need. Now our problem is to set the correct transparent color
in the appropriate struct. This should be a MWIMAGEHDR. - but we only have
an id to the pixmap we are using - how do we get to the appropriate header?
-- As Jordan said, there aren't yet transparent blitters implemented
in the fblin*.c files, so this won't work yet. The first fix is to implement
the ROP case in your fblinXXX.c driver. Then, you should (once)
copy the image into a GrNewPixmap, and destroy the image id. At that
point, you can use GrCopyArea with an ROP (since the pixmap is
based on a PSD), which will end up passing the ROP to the
driver blit function.
