Subject: st/mesa: avoid exposing EXT_texture_integer for pre-GLSL 1.30
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ebbd34a468a9e8f3f4d8900be38755d77a662f1f;p=mesa.git

st/mesa: avoid exposing EXT_texture_integer for pre-GLSL 1.30

For drivers building up to GL(ES)3, only expose the actual extension if
the API will let it be used (e.g. via overrides/debug flags that enable
higher versions).
