But if I call fillRect and don't do that, I actually don't get to see anything
on the display. Is there another way of showing the results of a KisPainter 
action?

The first tool I made, for testing purposes, used fillRect, which should work, 
shouldn't it? And if I use KisPainter's bitBlt to push the raw pixel copies 
back, then undo/redo should work too, I guess. Only then I have to get the 
image data back into KisPixelData again.

Okay, so I can scratch all that. That code was still present in 
kis_tool_selecetion_rectangular, so I thought it was necessary.
