Further simplification of AA regime 

Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good.  Fast AA
in accelerated canvas uses SMAA with tweaks suggested by David Beinder.
Good AA is super-sampled x2.

Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves.  Best is removed as it mostly affects text rendering
and not line drawing (as our text is)
