An extra
painter.end() before
composedOffscreenImage = composedOffscreenImage2;
seems to reduce the time required for the function significantly (panning large pixmaps feels less jerky).

Is composedOffscreenImage2 really necessary in the first place?

Also, resize() calls both newOffscreenImage() and forceRedraw()

    Cheers mate, I'll have a look and add this to next update. I wanted to improve the drawing and zooming (image) code anyway
