The mouse events should be fairly easy to figure out (if not let me
know) so here's the GDI+ stuff you'll need: http://www.bobpowell.net/changing_resolution.htm

to keep the ghost image under the mouse pointer. There are three
problems:
(1) if the ghost image is dragged so it is partially off the edge of
the screen, scrollbars appear. This not only looks bad, it can cause
the page to autoscroll...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
