Fix

Restrictions were added in GLSL 1.30 to allow indexing of arrays with
integral constants only. Earlier versions (GLSL <= 1.20 and GLSL-ES <=100)
should allow any sort of sampler array indexing (i.e. Non constant
expressions).

Mesa already has this in place but seems the checks fail in case of GLSL-ES ver
being 100.

Proposed patch
