Subject: Make w3mimgdisplay work with st

Before this patch draw() calls drawregion which calls xdraws and then
updates whole window in one call thus overdrawing anything drawn by
w3mimgdisplay. After moving XCopyArea to xdraws it only updates the
regions which are being updated by XftDraw* functions. It may do a few
more calls to XCopyArea with this patch.
