	* gdk/win32/gdkdrawable-win32.c (_gdk_win32_drawable_release_dc):
	Call ReleaseDC() on DCs acquired with GetDC() (for windows), and
	DeleteDC() on DCs acquired with CreateCompatibleDC() (for
	bitmaps). According to MSDN, this is the correct thing to do, even
	if always using DeleteDC() seems to have worked fine in
	practice. (#337491)
