- * Revision 1.5 1998/05/20 20:53:53 curt

- * Made a fgTILECACHE class.
- *
- * Revision 1.4 1998/05/16 13:09:57 curt
- * Beginning to add support for view frustum culling.

- * Minor transformation adjustments to try to keep scenery tiles closer to
- * (0, 0, 0) GLfloats run out of precision at the distances we need to model
