From eba527bf9ffc2fd67c44fb77104107556f509b49 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 29 Aug 2011 09:37:24 -0700 Subject: mesa: Remove API facing bits of EXT_paletted_texture and EXT_shared_texture_palette This was also discussed at XDS 2010. However, actually making the change was delayed because several drivers still exposed these extensions to significant benefit (e.g., tdfx). Now that those drivers have been removed, this code can be removed as well. v2: A lot of bits that were missed in the previous patch have been removed.
