on some platforms (osx) with authentication problems.
Move glossmap formula to getspecular shader
Rename some shader to improve their meaning
Update graphic restriction

This should fix bug #1519
Refactor IBL gen code
Implement specular IBL properly
Use clamp instead of max(0, dot(normalized, normalized))
