Where gfx.webrender.all is false by default (as it was for me): how can 
a person test the pros and cons of an override to true?

Whilst I'm not into benchmarking/comparisons (I'm not a speed freak), I 
am aware of things such as MotionMark 1.2

What's the implication of finding it false by default?

I overrode gfx.webrender.enabled to true in _89_ on FreeBSD after 
stumbling across 
<> (not specific 
to FreeBSD, from when _88_ was nightly). Now reverted to its default, 
false, I'll no longer override.
