/* gdkgeometry-win32.c: emulation of 32 bit coordinates within the
- * limits of Win32 GDI. Just a copy of the X11 version, more or less.
- * Probably totally bogus in functionality. Just a quick hack, to
- * get the thing to build. Need to write some test code for it.
- * Well, need to find out what it is supposed to do first ;-)
+ * limits of Win32 GDI. The idea of big window emulation is more or less
+ * a copy of the X11 version, and the equvalent of guffaw scrolling
+ * is ScrollWindowEx(). While we determine the invalidated region
+ * ourself during scrolling, we do not pass SW_INVALIDATE to
+ * ScrollWindowEx() to avoid a unnecessary WM_PAINT.
*
+ * Bits are always scrolled correctly by ScrollWindowEx(), but
+ * some big children may hit the coordinate boundary (i.e.
+ * win32_x/win32_y < -16383) after scrolling. They needed to be moved
+ * back to the real position determined by gdk_window_compute_position().
+ * This is handled in gdk_window_postmove().
+ *
* The X11 version by Owen Taylor <otaylor@redhat.com>
* Copyright Red Hat, Inc. 2000
* Win32 hack by Tor Lillqvist <tml@iki.fi>
* and Hans Breuer <hans@breuer.org>
+ * Modified by Ivan, Wong Yat Cheung <email@ivanwong.info>
+ * so that big window emulation finally works.
