// Since the second to last image is too old, we copy over the image from the previous buffer, but
// only for those regions that Qt didn't paint (because that would overwrite what Qt has just
// painted). This is the copyPreviousToCurrent() call below.
//
// After the call to copyPreviousToCurrent(), the current buffer contains the complete, full image of the
// whole window in its current state, and we call screen_post_window() to make the new buffer
// available to libscreen (called "posting"). There, only the regions that Qt painted on are
// posted, as nothing else has changed.
