[Qt-interest] Plans to improve the X11 backend?

No not again the usual finger pointing so common in open-source projects.
QT's raster engine is usually faster than QT's X11 backend, yes, but
at least to some extent this is because the x11 backend is in a really
bad shape. Its pretty sad to see what KDE/QT do to highly optimized 2D
drivers, all the required groundwork is already there - its just the
upper layer messing it up.

Yes, raster engines are good at specific things (like many small
operations), but terrible slow at others. And once you use a raster
engine, you loose all your abilities to accelerate certain operations
which can really benefit (like large blits, scaling, blending).

Of course if you use client-gradients in your themes everywhere
(oxygen), no wonder the X11 backend does bad.
