Subject: st/mesa: Enable the ARB_shading_language_420pack extension for 1.30+.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=adfd0123c8e70ff9bf1d8044a7e38029cfdf300f;p=mesa.git

st/mesa: Enable the ARB_shading_language_420pack extension for 1.30+.

Any driver that supports GLSL 1.30 should be able to handle this
extension, as it's entirely implemented in the GLSL compiler.
