Modifies triangle corner shaders to just approximate their coverage with
linear values that ramp to zero at bloat vertices outside the triangle.
For the vertex backend, since corners now have the same fragment shader
as the rest of the triangle, we fold them in with the other steps and
draw triangles in a single pass.
The geometry backend still draws triangles in two passes, as there is
not an apparent performance advantage in combining them.

SkAnimatedImage is a simple drawable for animating a GIF. Thread-safety
is left up to the client. At most two bitmaps are stored in the
drawable; one for the current frame and one for a frame that may need to
be restored. The backup frame prevents some cases where we would
otherwise have to re-decode from the beginning of the image.
The API lets the client set the time value, and decodes to match that
time.

- Callback for when the animation is complete
- Ability to use SkAndroidCodec
- Modify the loop count (or leave that up to client?)
- Better and/or client-specific caching
Other changes:
