From 553e37aa337783d468f218291f6de6a74e49289b Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 29 Mar 2016 15:31:05 -0400 Subject: [PATCH] mesa: allow mutable buffer textures to back GL ES images Since there is no way to create immutable texture buffers in GL ES, mutable buffer textures are allowed to back images. See issue 7 of the GL_OES_texture_buffer specification.
