Before integration of SoC terrain can commence a number of changes, fixes and cleanups needs to be done.

Short term:

• Normalize coordinate systems. Terrain is in xz plane, y is height!. Correction: use XY when talking about "heightmap space" coordinates but xz+y when in 3d coordinates.
• Redo the LRU stuff to use better timing source
• Material maps / base material should behave like old bruteblock with addition of possibility to add explicit alpha-maps on top of materialmap Additional pairs not yet supported!
• Support for 32-bit indices when needed
• Only generate indices once per block resolution, not per cell.
• Reformat code a bit to conform to CS standards.
• Rewrite the feeders to only have one instance of them for several cells.
• Rewrite the factory/instance interaction. Currently it only allows one instance to be created from a factory and nothing is stored on a per-factory basis. Needs decisions ;)

Longer term, things that can be done after integration:

• The terrain collision should be unified in one place
• More LOD control settings. Biggest/smallest tesselation etc.
• Atm only triangle edges<->terrain is handled in the terrain collision code, which works for small triangles. Need to add terrain edge<->triangles too.
• Inter-cell LOD handling to avoid cracks.
