Add textured line overlay rendering. Change terrain height calculations to be triangulation-dependent for improved accuracy. Add triangulation-dependent terrain normal function. Support separate S/T wrap modes for textures. Rename CVector2D_Maths since it no longer conflicts with simulation CVector2D. Coalesce freed chunks in vertex buffers, to avoid excessive fragmentation. Add some things to help debug vertex buffer allocation a little. This was SVN commit r9929.
