ImageList updates

Tue Sep 10 23:21:09 CDT 2002
This one depends on the commctrl.h patch.
ChangeLog
-- Rewrite the drawing code. It now is much smaller,
easier to follow, and faster. Moreover, it now
supports the dwRop operation, and it is in good shape
to support the missing features.
-- draw the dragged image semi-transparently (will work
when we support alpha blending)
