Bug 1091 - WM_MOUSEWHEEL (scroll-event) not handled correctlly

Browse Source 
* clutter/win32/clutter-event-win32.c (message_translate): The
	coordinates in a WM_MOUSEWEEL message are given relative to the
	screen so they need to be converted to client coordinates before
	use. Thanks to Roman Yazmin.
