This new API is built upon SDF text atlas code from the GPU backend. Unlike using the GPU
backend to draw text, this set of interfaces allows the client to render the SDF glyphs. The
client issues text draws to potentially multiple targets and then the client flushes. The
client then gets commands from Skia with data to put into a texture atlas and vertices to
draw that reference the texture. The client is responsible for creating the texture, uploading
the SDF data to the texture, and drawing the vertices provided by Skia.

Right now the native font platform implies what emoji formats are
supported, and we hope to support more than one per platform. Let's
get these formats out of the name.
As with most other font-y things, only the NativeFont bots are going to
get back anything interesting now. The others will see no emoji font
and an empty emoji sample text string.
I'm going to look at a pre-baked testing SkTypeface that serves as an
emoji font for the non-NativeFont bots next.

This does math on the sampled color. In order to do that math in the
destination color space, I split the behavior up - the threshold FP
now operates on the input color, and we construct a series with a
simple texture effect (possibly wrapped in a color xform), then the
threshold.
I also added a GM that verifies this behavior. All other GMs using
this effect were operating on a layer source, which is always
created in the destination color space. The new GM explicitly makes
a DAG with an image source, so the alpha threshold filter needs to
handle any color space mismatch.

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.

AFAICT none of our clients use this entry point and it is tangling up efforts to add a new parameter to the BlurImageFilter.

Adding a GM (Golden Master) image test in Skia to reproduce the bleed
black issue in Chrome. This would allow regressions to be caught in
Skia's status page before being rolled into Chrome.

The HSW backend does still look a little wrong, but improved,
and the others seem fixed. Can you see how this affects your
test cases, layout tests, etc?

Consolidates op factory functions to a rewritten GrRectOpFactory.
Removes GrRenderTargetContext::drawNonAAFilledRect() in favor of creating and adding ops directly by the callers.

This began as cleaning up SkSpecialImage.h & spiraled out of control from there.

Moves cubic root finding logic out of GrPathUtils and
PathOpsCubicIntersectionTest, and unifies it in SkGeometry.
"Normalizes" the homogeneous parameter values of the roots, rather
than the cubic inflection function. Does this normalization by
twiddling the exponents instead of division (which causes a loss of
precision).
Abandons the built-in derivatives in GrCubicEffect. These don't have
high enough precision on many mobile gpus. Instead we pass the KLM
matrix to the vertex shader via uniform, where we can use it to set up
new linear functionals from which the fragment shader can calculate
the gradient of the implicit function.
