In GLSL versions 1.00 ES, 1.10 and 1.20, Mesa includes
some built-in functions which shouldn't be present in
that version, namely:

   genIType abs(genIType x)
   genIType sign(genIType x)
   genIType min(genIType x, genIType y)
   genIType min(genIType x, int y)
   genIType max(genIType x, genIType y)
   genIType max(genIType x, int y)
   genIType clamp(genIType x, genIType minVal, genIType maxVal)
   genIType clamp(genIType x, int minVal, int maxVal)
   genType trunc(genType x)
   genType round(genType x)
   genType roundEven(genType x)
   genType modf(genType x, out genType i)
