I've been thinking that we could reduce cpu/gpu work while dragging a
clip, by painting the contents of AudioClipViews to a QPixmap, and on
each call to AudioClipView::paint(), reusing the part of the previous
pixmap that was visible, and still is visible.
We'd have to watch out for things that change a clip's appearance like
changing the soft-selected state, and then repaint the whole pixmap.
But then the performance while dragging a clip should be similar to
while scrolling.
Remon, what do you think?
