From bde8bd99b64876b47f9d335320eb1ad5b3be8d9d Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 30 Aug 2011 17:24:13 -0700 Subject: mesa: Remove EXT_texture_env_combine extension enable flag All drivers remaining in Mesa support this extension. This extension is either required or optional features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. The existing support is already partially broken in Mesa (e.g., querying GL_TEXTURE_ENV_MODE in OpenGL ES 2.x). This patch does not change the situation in any way. It looks like the only hardware supported by Mesa that cannot do ARB_texture_env_combine is pre-NV10 NVIDA chips. It appears that these chips cannot do the GL_SUBTRACT mode. Based on looking at older copies of nvOpenGLspecs.pdf found on the net, NVIDIA never supported ARB_texture_env_combine on those chips either. This extension was previously not supported on mach64, mga (G200), r128, savage, sis, and tdfx (Voodoo Banshee and Voodoo3).
