Destructor.
| btVector3 DtTileData::topNE |
The 8 points in geocentric required to draw the tile in the debug drawer.
| btVector3 DtTileData::topNW |
| btVector3 DtTileData::topSE |
| btVector3 DtTileData::topSW |
| unsigned int DtTileData::lastUsed |
The last time this tile was used.
Necessary for deciding which tiles to page out.

The number of triangles this tile, and therefore its collision object, contain.
Used for estimating page out gains.
