c6052ac41a Put back the 0.5 bias in the shader. Only adjust the radii for the geometry, not the radii constants. 
After working through this with Jim, this is more mathematically correct, and also accounts for the inner radius.

09bf666233 Remove the 0.5 bias from the ellipse edge function. This makes coverage drop to zero before we get clipped by the rasterizer (i.e. ensures the generated ellipse is inscribed in the geometry).

bb2ff94e22 Switch to vertex colors rather than uniforms for color in Ellipse/Circle/RRect/DRRect 
[Notes:]
- Performance delta on desktop looked like noise. I'm curious what the results will be on low-end mobile GPUs. I'm still trying to figure out how I determine that with perf, etc...
- There appeared to be a single one-pixel image diff while running dm, if I'm understanding the results of skdiff correctly, so that's probably good news?
- Should I include anyone else on the review?

bed1ed6eac Test SkAndroidCodec for more types 
Now that SkAndroidCodec supports all types, stop selectively running
its tests for the types supported by BRD.

For the tests that actually require BRD support (i.e. partial
scanlines), change the method name from supports_scaled_codec to
supports_partial_scanlines to be more accurate today.

Use the name SkAndroidCodec instead of SkScaledCodec.

c1eb311f4e SkNx refactoring 
- add back Sk4i typedef
  - define SSE casts in terms of Sk4i
      * uint8  <-> float becomes uint8  <-> int <-> float
      * uint16 <-> float becomes uint16 <-> int <-> float

    This has the nice side effect of specializing uint8 <-> int
    and uint16 <-> int, which are useful in their own right.

There are many cast specializations now, some of which call each other.
I have tried to arrange them in some sort of sensible order, subject to
the constraint that those called must precede those who call.

fff055cc5f SkHalfToFloat_01 / SkFloatToHalf_01 
These are basically inlined, 4-at-a-time versions of our existing functions,
but cut down to avoid any work that's only necessary outside [0,1].

Both f16 and f32 denorms should work fine modulo the usual ARMv7 NEON denorm==zero caveat.

In exchange for a little speed, f32->f16 does not round properly.
Instead it truncates, so it's never off by more than 1 bit.

Support for finite values >1 or <0 is straightforward to add back.
>1 might already work as-is.

9a1ed5d81d skia: Add support for CHROMIUM_image backed textures. 
I created a new abstract base class TextureStorageAllocator that consumers of
Skia can subclass and pass back to Skia. When a surface is created with a
pointer to a TextureStorageAllocator, any textures it creates, or that are
derived from the original surface, will allocate and deallocate storage using
the methods on TextureStorageAllocator.
