Review Request: KColorCombo: using roundedRects instead of rects.

[Ariya Hidayat]

If you backport it, there is a chance of potential slighty/miniscule
performance impact. Drawing antialiased rounded rectangle might
provoke the slow code path in most paint engines. The actual slow-down
depends on a lot of factors and will be difficult to predict.

My take: don't take the risk.
