Use the signed GET_X_LPARAM() and GET_Y_LPARAM() to extract x and y

Browse Source 
2003-03-14  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkevents-win32.c: Use the signed GET_X_LPARAM() and
	GET_Y_LPARAM() to extract x and y coordinates from an LPARAM or
	DWORD, and not the unsigned HIWORD() and LOWORD(). Systems with
	multiple monitors can have negative coordinates on some of the
	monitors. (partial fix for #99496, Arnaud Charlet)
