So current theming code doesn't fit and all theme painting should be 
integrated in 'its own implementation'.
This is something new to me, but it's better to start to test it cause 
we know enough.

Also I'd like to invite Andre to this thread cause it wrote a test for 
that some months ago.

Andre, is it something wrong with tests, why patch wasn't accepted?
