The toolbar refresh slowness (which has also to some extent Autocad) depends (I
guess) of app's mixing of DIB and DDB ops. Not solvable by current state of the
engine, it should handle DDB directly too without having to convert to an
forth, so co-operate with wineX11.drv internals which, because of being an
"external" part of wine (and, mostly, because I don't want to rebase it on each
change in winex11 !) it can't do now.

About the transparency, I've noticed that one too, but I have no time right now
to investigate it in depth. It should be something trivial, indeed.... Maybe on
next months, but I'm not motivated anymore to do hard development on DIB engine
now. AutoCad works and that was my urgent problem.
I lost the hope to see the engine into mainstream some time ago....

About the constraints, I'm happy to hear that :-)
I've seen that the engine, in some graphic parts, pass more tests than wine GDI
itself :-) I also have an app that behaves (graphically) better with the engine
than without, but usually it's the opposite, the engine has still some missing
points.

Ciao
