Replace almost all texture uses with calls to the new system. Add some anistropic filtering to terrain textures. Let Atlas load terrain texture previews partly-asynchronously by polling. Fix inefficient texture colour determination for minimap. Remove unused global g_TerrainModified. Change GUI texcoord computation to be less efficient but to cope with dynamic texture changes. Fix GUI renderer effects leaving bogus colour state. This was SVN commit r8099.
