// Revision 1.11  2004/09/14 00:13:29  jackson
// Timers are now handled in a second thread and post messages into the main threads message queue. This makes timing much more consistent. Both win2K and XP have a minimum timer value of 15 milliseconds, so we now do this too.
//
// Revision 1.10  2004/09/13 21:18:32  pbartok
// - Added Z-Ordering methods
//
// Revision 1.9  2004/08/24 22:35:44  pbartok
// - Refined definitions for CrossingEvent
//
// Revision 1.8  2004/08/20 19:11:56  jackson
// Use IntPtrs for ClientMessage extra data (TODO: This will screw up on 64 bit systems)
//
// Revision 1.7  2004/08/19 21:51:59  pbartok
// - Removed packing hints (Paolo suggested this a while back)
// - fixed colormap type
// - Added default Atom types
// - Added Screen and color structs and enums
//
// Revision 1.6  2004/08/09 20:56:18  pbartok
// - Added GrabMode enum
//
// Revision 1.5  2004/08/06 23:17:44  pbartok
// - Fixed Refresh and Invalidate
//
// Revision 1.4  2004/08/06 21:30:56  pbartok
// - Fixed recursive loop when resizing
// - Improved/fixed redrawing on expose messages
//
// Revision 1.3  2004/08/06 15:53:39  jordi
// X11 keyboard navigation
//
// Revision 1.2  2004/08/06 14:02:33  pbartok
// - Fixed reparenting
// - Fixed window border creation
//
// Revision 1.1  2004/07/09 05:21:25  pbartok
