It's better than nothing, so don't let me stop you.
But without panscan support it's not going to give the right results
e.g. when that feature is used.
Try for example "-panscanrange -1 -panscan -0.5" (this is supposed
to scale the video to half the window size), I guess your code will
produce mouse coordinates that are quite off.
I don't know what options there are on OS/2, but most overlay based VOs
nowadays use calc_src_dst_rects to just handle all these options
(in particular panscan and border-pos-x/y).
