Unused strings

[Michi Henning]

In NuxGraphics/RenderingPipeAsm.cpp, on lines 1272 and 1376 are definitions for AsmFrgRect. However, they are not used in the scope where they are defined. It's not clear to me whether they should be used but, accidentally, were not, or whether the definitions should be deleted.

The AsmFrgRect shader prog and I think all the Asm rendering pipe shouldn't be used at all because all the modern GPUs have GLSL support and can compile/run the GLSL equivalent shaders. It's very rear to find a GPU that can only use ARB shaders and I think those GPUs don't have support for vertex shaders either and they can't run nux anyway... (not 100% sure on that though!!!) Maybe we want Unity to run in some very old GPUs and that's why ARB support was not removed?

In that case I'd check with duflu to see whether there is any realistic scenario under which this might still be needed. If not, I'd ditch the lot. Code that doesn't exist can't harbour any bugs…
