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

[Clemens Eisserer]

Hi,

Does anoybody know how Nokia does validate painting performance?
I know from the development of "my" XRender backend for Java2D that
Sun has quite a few internal tools to monitor performance like this -
ranging from benchmarks which test primitive performance (blits,
lines, gradients) to more high-level stuff like widget exposure and so
on.
I asked that question a few times before, but never got an answer :/

Wouldn't do any good. XRender usually is accelerated in hardware, and
if not there are already SSE2/arm-neon/ optimized software routines
available.
