// Revision 1.2 2006/04/02 01:52:44 kkurbjun
// Update adds prboom's high resolution support, also makes the scaling for platforms w/ resolution less then 320x200 much nicer. IDoom's lookup table code has been removed. Also fixed a pallete bug. Some graphic errors are present in menu and status bar. Also updates some headers and output formatting.
