// Revision 1.9 1998/07/06 21:34:34 curt
// Added using namespace std for compilers that support this.
//
// Revision 1.8 1998/07/04 00:54:30 curt
// Added automatic mipmap generation.
//
// When rendering fragments, use saved model view matrix from associated tile
// rather than recalculating it with push() translate() pop().
//
// Revision 1.7 1998/06/12 00:58:05 curt
// Build only static libraries.
// Declare memmove/memset for Sloaris.
//
// Revision 1.6 1998/06/08 17:57:54 curt
// Working first pass at material proporty sorting.
//
// Revision 1.5 1998/06/06 01:09:32 curt
// I goofed on the log message in the last commit ... now fixed.
//
// Revision 1.4 1998/06/06 01:07:18 curt
// Increased per material fragment list size from 100 to 400.
// Now correctly draw viewable fragments in per material order.
//
// Revision 1.3 1998/06/05 22:39:54 curt
// Working on sorting by, and rendering by material properties.
//
// Revision 1.2 1998/06/03 00:47:50 curt
// No .h for STL includes.
// Minor view culling optimizations.
//
// Revision 1.1 1998/05/23 14:09:21 curt
// Added tile.cxx and tile.hxx.
// Working on rewriting the tile management system so a tile is just a list
// fragments, and the fragment record contains the display list for that fragment.
