753403cb64 Add new GM to verify Plots marked correctly during regenerate.
There was an issue on Android where a client was drawing a small bit of text,
and then a large chunk of text below it. On the next frame they started fading
out the text and then swapped out all of the large chunk of text. We were not
marking the Plot containing the small bit of text as still in use in this case,
so it was getting overwritten by later uploads. That bug has been fixed,
but this GM tests that codepath.

5ceda554f5 Fix stroked round capped circular arc batched with filled circle.
A stroked arc with round caps was batched with a filled circle. The circle op
code would choose a GeometryProcessor configuration that expected round cap
centers as vertex attributes. However, the tessellation code for the filled
circle would not put in dummy round cap centers and then didn't advance the
pointer into which vertex data was being written by the expected vertex
stride.

c32aeb326e Fix two GPU image filters handling of subset inputs
Added a GM that demonstrates the bug. Should draw a blur with
the center masked out, and a circular blurry shape that's
roughly the inverse. On raster, this was already the result.
On GPU, the blurred/eroded layer becomes a subset with an
origin other than (0,0), and that layer was shifted.

I *think* this is the correct fix - we are including 'offset'
in the texture matrices, but that's just based on the crop
rects and adjustments from each filter. We still need to adjust
the texture coords for the subsets themselves.

0a0304c426 Add experimental API to draw a set of SkImages in one SkCanvas call.
The client provides a src and dst rect for each image as well as
a bitfield that indicates whether each edge of the image should be
antialiased. This per-edge AA is useful for tiled compositors.

Rather than take a full SkPaint this API only takes an alpha, a filter
quality (which is pinned to kLow), and a blend mode. This is a likely
point of future evolution.

Currently the API is only fully implemented for kSrcOver on the GPU
backend. With other blend modes or on other backends AA will be ignored
for images that do not have all four edge AA flags set.

72535fb55a Reland "Reland "Implement an explicit binary search-based analytic gradient colorizer""
This is a reland of f065907ccc

3rd time's the charm:

The new analytic gradient shader was sporadically triggering violations of the coverage as alpha
compatibility optimization. Unfortunately, even when using the same device and random seed for the
test, the bots did not always reproduce the error. However, we identified the likely cause of the
violation.

The test requires that all output channels are less than the input alpha, which it uses to validate
whether or not the shader is modulating its values by the input alpha. This test does not pass if
the RGB values are greater than 1. The original version of the analytic gradient shader used half4s
for its scale and bias values. Given the threshold limit for hardstops of 0.00024 (SkNearlyZero),
a very small interval that is not treated as a hardstop can create a scale or bias of over 4000.
This moves into the very imprecise region of 16-bit floats, making it plausible that the gradient
outputs colors greater than 1, due to rounding. The kicker is that the random test generation for
stop locations does not use a uniform distribution, but is instead biased towards the remaining
interval, which increases the likelihood of generating a small interval that is not treated as a
hard stop. We are keeping this behavior since ill-conditioned gradients are useful in testing.

2213ee94c7 Add support for per-edge AA to GrTextureOp.
Outsetting in perspective case outsets the original homogeneous quad
points rather than the homogenized 2d points in order to avoid seaming
issues along shared edges.

Currently there is no way to trigger this from the public API and it
is tested by directly accessing GrRenderTargetContext from the added gm.

cfe1264d74 GrTessellator: two fixes for boundary simplification artifacts.
The "pointy vertex" test was only considering the distance from the
next (outgoing) edge to the previous point. It must also consider the
distance from the previous (incoming) edge to the next point. If
either are less than a quarter pixel, the vertex is considered pointy
and should be removed. (884166)

Also (887103), when an interior region was completely removed due to
boundary simplification, it would leave a degenerate edge consisting
of the same vertex. So avoid introducing a join edge when prev == next.

Bug: 884166, 887103

dcc85fc610 Implement an explicit binary search-based analytic gradient colorizer
Provides a reasonably flexible fragment processor that defines another
colorizer implementation for gradients. It can support up to 8
interpolation intervals (which is 16 colors if every stop is a hard stop
or 9 colors if every stop is a smooth transition). It
supports mixtures of hard and smooth stops. It is conditionally compiled
into versions specific to the interval count (so it can produce up to
8 shader variants).

The GrGradientShader controller does not remove the single and dual
interval colorizers, which are useful specializations of this explicit
binary search colorizer. Similarly, since it can only handle up to 8
intervals, the texture colorizer is still used as a fallback.

Currently it does not employ capabilities detection to determine if the
hardware can support the number of required uniforms, which can become
substantial for the larger gradient configurations.

8f5a7a6f50 first start on a P3 GM
We don't have anything drawing colors outside sRGB,
but now that we've got SkPaint::setColor4f(), that's easy.

Looks like we have lots of work to do.

Pin GrColor4f floats before converting to unsigned.
Underflowing floats would get pinned to 255 spuriously
instead of to 0.  I think this fixes the failing CQ
bot, and the white square problem.

2f2757fa6b ccpr: Implement stroking with fine triangle strips
Implements strokes by linearizing the curve into fine triangle strips
and interpolating a coverage ramp for edge AA. Each triangle in the
strip emits either positive or negative coverage, depending on its
winding direction. Joins and caps are drawn with the existing CCPR
shaders for triangles and conics.

Conic strokes and non-rigid-body transforms are not yet supported.

2a4f983c94 Remove GrSurfaceOrigin from GrSurfaceDesc.
This field has no interpretation at the GrTexture/GrGpu as the orientation is
handled at the GrSurfaceProxy level.

This change requires GrGpu to accept a GrSurfaceOrigin when creating a texture with initial data. The origin refers to the texel data to be uploaded. Longer term the plan is to remove this and require the data to be kTopLeft. Additionally, kBottomLeft will only be allowed for wrapped texture/RTs as this evolves.

aae533e418 Revert "Remove SkImage deferred texture image data APIs."
This reverts commit 4f5e1d4ff3.

Reason for revert: Unfortunately, we need this in Chrome for a bit longer. Working on understanding why the new path led to regressions. Will re-land this once the new path sticks.

0215e39d7e Transform vertices for distance field glyphs on CPU.
This allows batching of DF draws with different view matrices.

For perspective matrices this means the transformed position vertex
attribute must have w values. Currently, non-perspective DF draws still
use 2 component positions, though this could be changed in the future.
Consequently, perspective draws can batch with other perspective draws
but not non-perspective draws.

Adds a GM to test batching and reusing the same blobs with both perspective
and non-perspective matrices.

e95a62faa0 add some lowp gradient stages
I was originally going to add these to help test a lowp dither, but
after looking at diffs I don't think lowp dither is a good idea.

Non-dithered lowp gradients look fine to me so far.

I'd have done conics, but they scare me.

b433c5691b Adjust GPU YUV -> RGB (JPG) conversion
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
