EEVEE: Intel Shader Compiler Bug
When using Intel GPU EEVEE did not display anything. This was due to an
internal shader compilation bug inside the intel drivers. We had fixed
this for other vertex shaders. The same change we have to apply to other
vert shaders that want to limit the need of Matrix multiplications.
