qcam: Support scaling of the viewfinder
The viewfinder is drawn using a QLabel. This could support scaling through QLabel::setScaledContents(), but in a very inefficient way. To maintain reasonable efficiency, turn the viewfinder into a QWidget and draw the image directly using a QPainter. No performance change was noticed running on a fast x86 machine, and performance was 60% higher when scaling up to full screen compared to QLabel.
