* Source/win32/WIN32Server.m (-windowEventProc:, -process_mouse_event:):
Start tracking the mouse at the first mouse movement (as suggested in
a note at MSDN documentation) so the window receives the WM_MOUSELEAVE
message when the mouse leave the client area. I don't use the message
WM_NCMOUSEMOVE, as suggested by Fred, because when the user moves
fast the mouse this messages is not generated. But we receive the
WM_MOUSELEAVE message no matter if the mouse move fast or not. This
approach make unnecessary handle the message WM_NCMOUSEMOVE. I also
remove a redundant line in WM_MOUSELEAVE.
