Right now when we turn rects into quads we use a vertex order compatible with a tri fan rather than a tri strip.
I wanted it to be the case that the same code could be used to generate a non-indexed mesh for a single rect or indexed using the quad index buffer when batching. Triangle fanning is not available in all APIS (e.g. is emulated in ANGLE and not supported in Metal) so it seems better to use a triangle strip over a fan in the single rect case.

All of the published coefficients assume math is being done on bytes, and
that 128 is the encoding of 0 (in the biased Cb and Cr values). When
sampling an A8 texture, though, GPUs typically decode as byte/255. Thus,
128 ends up slightly larger than 0.5. To fix this, just adjust the bias
terms to be scaled by 128/255, rather than 0.5.
I also changed some of the other coefficients to be higher precision,
based on the values in ITU-T T.871.
This originally surfaced as a Chromium bug where an all-black JPG decoded
to (1/255, 0, 1/255) on GPU. I've added a GM that encodes a color cube to
JPG, then draws from the encoded data. GPU and CPU (libjpeg) still
disagree in many cases, but the newer version performs much better
(diffing gl and 8888 configs):
Previously: 95.2% of pixels differ, max diff of 2, avg diff of 1
Now : 65.4% of pixels differ, max diff of 1, avg diff of 0

This fixes an Android rendering bug where radial gradients were being used
for "clipping" (via DstIn blend mode). The gradient stops were placed at
(0, 0.999, 1), which caused our table quantization to drop the last stop.
kThree_ColorType now means "0, any t, 1". The old (special-case)
kThree_ColorType is now called kSymmetricThree_ColorType.

This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

Expand the sweep gradient definition to include a color stop angular range ([0, 360] by default).
Color stop positions in [0,1] are mapped to this range, and drawing outside is controlled by a
tile mode param.
This is closer to the CSS gradients spec and allows us to use fewer color stops in Blink conic
gradients.
Impl-wise, the remapping is effected after t calculation, and before tiling.
