From b6d29de2c443df2aa670a70545d2e1e68ef57f45 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 13 Aug 2014 19:30:48 +0200 Subject: [PATCH] mesa: fix texstore with GL_COLOR_INDEX data This got broken by 3dbf5bf6571e0c9d3e4febce01dea82be190d9d2. GL_COLOR_INDEX data is still supported (in legacy contexts), but the new texstore_swizzle path cannot handle it (and didn't detect this). Unfortunately there's no piglit test trying to specify textures with a GL_COLOR_INDEX source format, and I don't really understand how all the color map stuff which is used by this works, but this caused conform failures (with a reported mesa implementation error when trying to figure out the color mapping).
