[Mesa-dev] [PATCH 2/9] ff_fragment_shader: Use binding to set the sampler unit

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

This is the way layout(binding=xxx) works from GLSL.  The old method
just happened to work (and significantly predated support for
layout(binding=xxx)), but future changes will break this.
