[Mesa-dev] [PATCH 5/6] meta: Always enable GL_EXT_texture_array in mipmap shader

[Ian Romanick]

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

'#extension foo: enable' is harmless.  The functionality is only
actually enabled if the extension is supported.  The shader won't use
the functionality if it's not supported, so we're fine.
