irrlicht/source/Irrlicht/CD3D9Driver.cpp
cutealien 02165eccc8 CD3D9HLSLMaterialRenderer now implementing IMaterialRendererServices itself 
Basically now the same as GLSL material renderer already worked.
Before it was using IMaterialRendererServices from CD3D9Driver, but there had been several problems with that:
- The d3d9 driver called functions through the CD3D9MaterialRenderer interface, but CD3D9HLSLMaterialRenderer is not (or maybe no longer?) derived from that class. Reason it still worked was accidental luck - the same functions had been in the same order and due to casts the compiler wasn't noticing it was calling the functions of an unrelated class.
- It was making calls to set shader constants depend on the currently set material in the driver. Which was not necessary and just prevents we can use the IMaterialRendererServices interface without setting the material first (how I found the bug).
Still some problems left for now:
- There's 2 ways to call shader constants. One seems to be only used by hi-level shaders which links constants to the shader. The the other only by low-level shaders which uses global (shader independent) registers.
So maybe this should be 2 interfaces? But not certain, glsl material renderer seems to prevent setting the global registers, but maybe those could be used additionally? I've still allowed it for now in HLSL, just in case it had it's uses.
- setBasicRenderStates probably should not be in IMaterialRendererServices. I'm not seeing any case where this isn't just passed on to the driver. And all classes using it have access to the driver unless I missed one. So probably can just avoid that additional indirection and kick that out of the IMaterialRendererServices interface.
