Also document that gl_FrontMaterial is no longer supported in Irrlicht 1.9 (this has been the case for a few years, I just never noticed this was changed as I never even knew that was possible in the past...). Will keep it that way is it's definitely going in the right direction (getting rid of legacy support and going towards OpenGL core instead),

What Irrlicht calls ShaderConstants is called uniforms by everyone else. So let's mention this at least.
Also reworked setVertexShaderConstant interface had an example for the old interface in the header.

This makes it possible to set high-level shader constants (which are attached to shader programs) to be set outside
of OnSetConstants.
IShaderConstantSetCallBack::OnCreate has it set automatically now so it works the same as OnSetConstants.
D3D9 and burnings both work different, so there hadn't been a problem with those.

Accessing IMaterialRendererServices outside of OnSetConstants can be useful and Irrlicht made this a bit too hard to access.
Also OnCreate allows actually for nicer code where initialization and update of shader constants are strictly separated (see changed example).

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.
