You changing way too many things without a single test. Lots of those areas
you touch will break oh so many apps.

For starters write some tests and verify what you doing is correct. You
should be able to write tests for all injected messages (send_mouse_event).
If you can't make an automated test, write a visual test for the rest and
send to wine-devel. Especially pay attention to all messages sent, and order
of calling hook, sending messages, modifying values returned from
GetCursorPos(). You breaking that.

And don't try to keep pointer inside Wine's window - this won't get past AJ.
