[Mesa-dev] [PATCH 1/4] st/mesa: emit sampler view declaration in bitmap shader

[Brian Paul]

In June 2015, Rob Clark started updating the tgsi utility code to emit
SVIEW declarations in various shaders (for polygon stipple, blitting,
etc).  These patches do the same for the Mesa state tracker.

The VMware driver will use this.
