I would worry that this might break applications.  Some apps specify
particular filtering modes for good reasons of their own; setting the
environment variable would cause those apps to silently produce
incorrect results.

As a general matter, I'd vote to use the software renderer for
fallbacks and for experimental rendering extensions; I wouldn't spend
too much time trying to optimize it for speed these days, since
accelerator hardware is ubiquitous and cheap.
