Begin commits to meet the string freeze deadline today (I hope I haven't missed it due to timezone issues):

* Warn on KolourPaint startup if the screen is paletted (e.g. 8-bit) since it's not really a supported configuration (I tried to support it in KDE 3 but bugs kept appearing; in KDE 4, I haven't had time to check all the code yet e.g. KDE 4 porting regressions + Tone Enhance & HSV effects)
