There is no portability factor. Only which toolkit is available.
As one of our engineers here said on our internal discussion (and goes
back to rasters comment):
"One of the neat advantages of Qtopia on Qt for Embedded Linux is that
there is little penalty in converting back and forth between a QImage
and QPixmap so we have used this extensively which makes quite a few
things much easier and more possible than if things are based on X11
where these conversions are expensive and you then need to put a bit
more thought in to it. "
