disable DAA

** Sheriffs, this is a bug fix that affects most curve drawing. **
** I've got thousands of diffs here, and probably missed a few. **
** If we could find a way to roll forward through any breakages **
** rather than revert this CL, I'd be very appreciative.  It's  **
** going on a month now trying to get this in.                  **

DAA and its ilk have fundamental problems dealing with overlapping
coverage.  While we think about how to solve them (and if they can
be solved at all), turn it off.

It took me a while to find one,
but fast/borders/borderRadiusDashed01.html is the smoking gun.
