Optimizations for analytic shadows.
Lots of changes here:
* Batch circle shadows with rrect shadows
* Avoid checking matrix and path conditions twice
* Remove lots of checks for 1/2 pixel radii
(needed before to force the rrect through the
regular GPU path)
* Fix scaling effect on ambient blur width
* Remove unused flags
