// $Revision: 1.10 $
// $Modtime: $
// $Log: XplatUI.cs,v $
// Revision 1.10  2004/08/11 22:20:59  pbartok
// - Signature fixes
//
// Revision 1.9  2004/08/11 19:19:44  pbartok
// - We had SetWindowPos and MoveWindow to set window positions and size,
//   removed MoveWindow. We have GetWindowPos, so it made sense to keep
//   SetWindowPos as matching counterpart
// - Added some X11 sanity checking
//
// Revision 1.8  2004/08/11 18:55:46  pbartok
// - Added method to calculate difference between decorated window and raw
//   client area
//
// Revision 1.7  2004/08/10 17:39:22  pbartok
// - Added GetWindowPos method
//
// Revision 1.6  2004/08/09 20:55:59  pbartok
// - Removed Run method, was only required for initial development
//
// Revision 1.5  2004/08/09 20:51:25  pbartok
// - Implemented GrabWindow/ReleaseWindow methods to allow pointer capture
//
// Revision 1.4  2004/08/09 17:02:29  jackson
// Get default window properties from the theme
//
// Revision 1.3  2004/08/09 15:56:44  jackson
// Remove defaults, these are handled by the theme now.
//
// Revision 1.2  2004/08/04 20:11:24  pbartok
// - Added Invalidate handling
//
// Revision 1.1  2004/07/09 05:21:25  pbartok
// - Initial check-in
//
//

// NOT COMPLETE
