Test KDevelop4 with --graphicssystem native

[Alexander Dymo]

I think we should just use native now. See below for details:

I don't have Qt 4.6-based system, but Qt vesion shouldn't matter much.
I've tried KDevelop with both raster and native. With my setup (Opensuse 11.2 
with opensource ati drivers), I can't tell the difference between raster and 
native.

Performance regressions were on systems with:
- linux kernel < 2.6.30
- old nvidia drivers
- proprietary ati drivers
- old intel drivers without UXA

Recent distributions (new ubuntu, opensuse, fedora) already have the new linux 
kernel and new intel drivers with UXA. With them, there should be no 
performance regressions with native.

There's still an open question about proprietary ati drivers, but Nikos 
Chantziaras reported no issues with catalyst and Qt 4.6. So it may be fine 
now. Also, with new distributions and updated radeon driver, people won't have 
to use commercial driver anymore.

I've tested my desktop with opensource radeon driver and Qt 4.5. There's no 
perceivable difference between native and raster.

So, yes, I do think we can switch to native. People on old systems may still 
use --graphicssystem=raster anyway.
