add low res terrain temperature texture per tile, with testing data #111
Merge remote-tracking branch 'origin/master' into temperature_111
Revert "add low res terrain temperature texture per tile, with testing data #111"

create separate terrain tile instead of temperature as attribute of the existing tiles

This reverts commit 0c1ae737401097b79780a9f4c18b29dcd3b71bb2.
use quadratic terrain tiles only (as needed), makes the code a bit simpler #111
minor height range fix #111
add some code to allow lower tile sample rate #111
move TerrainTile physx + rendering code to subclass #111
use more generic "value" instead of "height" in TerrainTile #111
group terrain tile levels: physical/attribure #111
Merge branch 'textureManager_125' into temperature_111
