Yesno.
Nuno ruled out most gradients, so the stuff became far less important and all 
gradients will be created in software (nVidia is notably faster but eg. 
cannot do multistop radial gradients as well)

Blending should work on most implemetations, so that you'll either have 
sufficient speed here or not (in case you wanna use another transition or no 
transition at all)

Only thing remaining is the masking - Qt uses back and forth Pixmap -> Image 
conversion here, so though the speed is still ok for small items (if you 
don't set scale to 10 or so ;) i'd like to avoid it.
(Requires working XRenderComposite(dpy, PictOpSrc, src, mask, dst))

If there're know issues i'll try to write a compile check (but if the Render 
implemetation does not even mentions an error and just paints crap, this will 
be hard to do)
Any infos about broken drivers for this case?

(Another option would be to make a config option instead an #ifdef - should 
not be the performance killer ;) )
