(may need to add support for directx8 and software?)

-made terrainNode use DynamicMeshBuffer, so it can use 32bit buffers. (no more size limits now on terrains!!! )
if the terrainNode loads an image over 256x256, it is set to 32bit, smaller sizes will use 16bit for better speed.

Optimized isBetweenPoints for vector2d
Added some virtual qualifiers for better readability
Added some terrain interface methods which are not properly working, yet

Changed the interpretation of MaterialTypeParam==0 in transparent materials. Before, it was interpreted as 0.5, now it's used as 0 (perfectly smooth transparency). This is slower than the old value, but you can achieve the same effect by specifying 0.5 as MaterialTypeParam.

Replaced transformBox by transformBoxEx to avoid major malfunction of the transformations when the transformation includes rotations.

Prevent b3d loader to load textures from unused materials. Other mesh loader might still suffer from this.

Added new mMeshManipulator method scaleTCoords to scale texture coords of a mesh. Added two new access methods to texture coords of vertices of a meshbuffer. This allowed to replace the template for planar mapping as well.

Added support for proxy meshes as source of the shadow volume. This enables the use of a simplified version of a mesh for the generation of the shadow volume, which can significantly improve the render performance with shadow volumes. Patch provided by tonic.
