workaround (patch)

I was affected by that problem too. When using sprite-based
animation (rapidly changing backgrounds) the animated image
becomes pixelated during frame changes. I've changed
GraphicsContextQt.cpp so it always uses
QPainter::SmoothPixmapTransform. After that change the problem
with non-smooth scaling disappeared and I didn't notice
any performance hit. Your mileage may vary though.
