This is for the conversion /to/ paletted textures. The conversion is necessary for csqc support. In the process, the conversion has been sped up by implementing a color cache for the conversion process. I haven't measured the difference yet, but Mr Fixit does seem to load much faster for the sw renderer than it did before the change (many months old memory).
