From 2c7f5fe2960362b266aeb8e1ed0ebea762131df5 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 16 Feb 2016 01:27:27 -0500 Subject: st/mesa: add ES sample-shading support We require the full ARB_gpu_shader5 for now, but in the future some other CAP could get exposed to indicate that only the multisample-related behavior of ARB_gpu_shader5 is available.
