Description Wei Wang 2007-05-18 18:11:59 UTC 
mesa Mesa: master 8a7f474c691dc077c081b59e30937e526400860f.

On intel platform (i965), I remove all 3D drivers and launch X for testing. Now it is under indirect context for sure and glxinfo shows that GL_EXT_paletted_texture is supported.
For the sake of testing whether this extension works: I generate a bitmap and supply it as a texture's image by specifying the internal_format as GL_COLOR_INDEX1_EXT, which is introduced by this extension we are talking about. And then call glGetTexImage() with format and type set to GL_COLOR_INDEX and GL_BITMAP respectively to get the bitmap data.
The behavior is that the bitmap data achieved later is not the same as the that generated originally.
See the case later.

Mass version move, cvs -> git

Closing, as mesa got rid of GL_EXT_paletted_texture completely in Aug 29 2011.
