Yes, use a simple QPainter to draw it directly on the canvasview widget. By the way, make sure
to use a QRegion Object to store the selection region.

Sven: Feel free to contact me in case you have questions/problems. And by the
way, if you have free time...we need a "new" dialog similar to the one in GIMP.
Make it a normal KDialog (no KFD) . We need widgets to select height/width of
the new image, color mode (RGB/CMYK/LAB/GrayScale) and background fill options.
