63f0354b6d Add support for directional lights.
Adds a new kDirectionLight_ShadowFlag which indicates that lightPosition
is a vector pointing towards the light, and lightRadius is the blur
radius when the occluder is at z == 1. For other values of z it will
scale linearly. The direction is specified in device space.

53d863c18c Enable tonal color for shadows by default.
This change swaps the sense of the tonal color shadow flag, so
tonal color will always be on unless explicitly disabled.

060d982036 Combine the ambient and spot alphas into the base color
for geometric shadows. 

This matches the analytic shadow approach better, and
is color space invariant.
Also includes cleanup in SampleAndroidShadows.

57061eea44 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
