From f6b7157550205a0633b4c2cb49a807d581176e21 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 10 Aug 2012 10:36:17 -0600 Subject: [PATCH] mesa: raise GL_INVALID_OPERATION in glGenerateMipmap for missing base image MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This seems to be expected by the WebGL texture-mips test. The error makes sense, but I haven't found (yet) any OpenGL documentation specifying this error condition. See http://bugs.freedesktop.org/show_bug.cgi?id=44912 Note: This is a candidate for the 8.0 branch.
