Subject: mesa/st: enable ARB_fragment_layer_viewport
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6c544e5413a6c551bf965817f7f238903b367b24;p=mesa.git

mesa/st: enable ARB_fragment_layer_viewport

If multiple viewports are supported, that implies the presence of a GS
and layered rendering, so we can enable ARB_fragment_layer_viewport as
well.
