No, it means blits are accelerated - thats the whole point in OpenGL :)
Normal 2d blits (under classic targets), are accelerated where acceleration
is (which means DirectX in reality, don't think xlib is much accel'ed?)

Ok, we'll see then.

With deprioritizing, I just mean we'll concentrate on OpenGL first (as thats
what we personally use in our own projects anyway), and when that is running,
and we're sure the API is perfect, we'll look into the classic targets.

Thats why Im afraid you'll be scared of with the current ClanDisplay... it
wasnt designed for low-level manipulation. We're just brewing on something
much, much better, and I don't want people scared off from something we're
currently improving.
