#1 Terrain texture does not map as expected

[Ted]

* Build & launch PigShooter
- View the ground/terrain from several different angles.

EXPECTED: Neatly gridded terrain textures.

ACTUAL: The terrain texture looks correct on some triangles, but is stretched -- sometimes to the extreme -- in others.

This is almost certainly related to accepting the default tx/ty values for the IndexedTriangleStripArray in libs/T3D/Sources/T3DTerrainMesh.java. The ideal solution would be for the T3DTerrainMesh object to have "normal" default behaviour, but to allow the developer-user to override, if they desire. This fix would almost certainly be in (or called from) createGeometryIND_TRI_STRIP()
