Document some shader behaviour

Browse Source 
S3DVertexTangents also documents that it's passed as TEXCOORD1 and TEXCOORD2, but easy to miss, so added some comments to the hlsl shader.
Also not all materials work well as base materials.

To demonstrate this, we create two materials with a different base
material, one with EMT_SOLID and one with EMT_TRANSPARENT_ADD_COLOR.
The role of the base material is to set the alpha (transparency)
and blending settings as used in the base material. Avoid the
EMT_NORMAL_... or EMT_PARALLAX... types as base materials as they
are internally shaders themselves and will only create conflicts with
your shaders.
