It contains 4 major enhancements: gaussian blur, shadow, glesv3 and glesv2 with GL_ANGLE msaa extensions, pus fix bugs/optimzation here and there.

How interdependent are those four chunks?  I.e. could the
gaussian blur bits be split into its own branch and
reviewed/stabilized/landed first, then the others in turn?  Or would
this require a lot of patch fiddling to extract it?  Just trying to
think how to divide and conquer efficiently.  :-)

And yeah, I can definitely help on test cases for shadow and blur.
Figure we'll want both functional tests and some perf tests.
