Well, for the moment it would remain a mixture. Using cairo for the
"missing pieces" that didn't use basebmp and were just empty "I can't
do it" stubs. But, depending on XOR cleanup foo, yeah, we'd hopefully
go that way.

ok, that's perfect from my side, and reduces my worry about busting
libreofficekit using stuff.

ok, though maybe the formats should be named LOK_TILEMODE_RGBA and LOK_
TILEMODE_BGRA. Cause in either case the A is in the same place. I'll
twiddle that when I merge.
