Just one other question regarding your use of these builds: Are these Mesa
builds with software rasterizers something you ship with Paraview as a
fallback for when hardware is not up to snuff, or for other certain
situations? Or will you always be using software rendering (OpenSWR?) going
forward? No hardware?
