My apologies. I considered the risk of this change to be minimum since
to disable server-side gradients would take just a single line. When I
pushed the commit I tried to ping the relevant developers and even let
the Mozilla developers know about the impending performance regression.
I consider the fact that cairo is hiding gradients from the drivers is
allowing *their* bugs to stagnant, and as our traces show they are in
widespread use across the desktop and so deserve acceleration.

However, I forgot to do this in email and so the warnings went amiss.
