From 507e71e45a2e46c6e01423ab00948a72f435396c Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 17 Nov 2011 17:19:12 -0800 Subject: [PATCH] i965: Add support for GL_ARB_depth_buffer_float under 3.0 override. This is not exposed generally yet because some of the swrast paths hit in piglit (drawpixels, copypixels, blit) aren't yet converted to MapRenderbuffer.
