From bd850cb4f2c77e2eb6716c865c40b9976633fc23 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 25 Apr 2013 12:06:23 -0700 Subject: [PATCH] i965: Remove GL_ARB_color_buffer_float from GL core contexts. Of the 3 controls in the extension, one was kept in GL core and the other two were explicitly deprecated and the reasonable default behavior was encoded in the spec. By not exposing the extension, we avoid shader recompiles when switching between float and unorm color buffers.
