* gdk/win32/gdkgeometry-win32.c (gdk_window_copy_area_scroll,
_gdk_window_move_resize_child): Call UpdateWindow() after
scrolling or moving/resizing the window. This causes a WM_PAINT
message to be sent to the window procedure. Improves scrolling a
lot, for instance in testgtk's "scrolled windows" dialog or
gtk-demo's "Text Widget".
Without calling UpdateWindow(), Windows generates a WM_PAINT only
when there is no other message in the queue. Thus, while you keep
moving the scrollbar slider and generating mouse messages, no
WM_PAINT messages are sent.
