- saving the entire vertex list for each tile with the tile records.
- saving the face list for each fragment with the fragment records.
- code to intersect the current vertical line with the proper face in

Fixed a bug where the tiles weren't being shifted to "near" (0,0,0)
Working on rewriting the tile management system so a tile is just a list

data file rather than calculating it on the fly.
Fixed polygon winding problem in scenery generation stage rather than
compensating for it on the fly.
Made a fgTILECACHE class.
