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.

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.

a7914d3a8e Implement textured gradients
Also clones SkGradientBitmapCache into GrGradientBitmapCache in the
gpu/gradients folder. But after cleaning up the old gradient code,
SkGradientBitmapCache will go away and SkGradientShader will have no
reference to the bitmap cache or support for building bitmaps.

The "new" GrGradientBitmapCache has been updated to hide the thread
safety responsibilities and gradient bitmap generation code that had
originally been a part of SkGradientShader.

8f685085af Implement 2-pt conical gradient layout
Add an FP that provides the two-point conical gradient effect. The
majority of the new FP's shader code is a straight forward port from
SkTwoPointConicalGradient_gpu.cpp. This FP is bulkier because of the
extensive calculations that go on in its overridden Make function.

To support 2-pt conical gradient's behavior of writing transparent
black in invalid areas of the conical interpolation, the contract of
gradient layout FPs has been updated to provide a flag in the y
component as to whether or not the fragment should be rejected.

A separate channel was used since negative values and large values are
perfectly reasonable for the untiled gradient layout to return (before
the value is then constrained into [0, 1]). It also seemed better to
avoid returning a problematic value like infinity or NaN.

10f7a1e075 Base Gradient FP Refactor
--

Redefines how gradients will be written in the GPU back-end:

They are split into three fragment processor components: master, layout, and colorizer.
The layout FP is responsible for converting the fragment position into an interpolant value, t.
Each high-level gradient--such as linear, radial, etc.--are implemented solely in a layout FP.
The colorizer FP is responsible for converting t into a color.
The master FP invokes the layout, clamps t into the proper domain, and then invokes the colorizer.
GrGradientShader provides factory functions to create FP graphs from SkGradientShader instances.
This pattern is documented in gpu/gradients/README.md.

Goals for current CL
====================

Outline the FP components by providing .fp implementations for the simplest gradients.
Defines a two-color single interval colorizer and a linear gradient layout, and the master effect.
A MakeLinear() factory function is provided that can convert SkGradientShaders that fit these constraints.
SkLinearGradient first attempts to use the new system, falling back to the original GrGradientEffect.

Future CLs
==========

To keep the CL reviews manageable, additional dependent CLs will be added that gradually replace past functionality.
A CL for each layout will be defined.
CLs for the different analytic colorizer cases and the textured gradient case will be defined.
Once the new system supports all current layouts and colorizer capabilities, all old GPU gradient code will be removed.
After this clean-up, analytic colorization can hopefully be expanded to reduce the usage of textured gradients.

10c3776b44 Remove GrTextureStripAtlas, textured gradients use independent textures
The texture strip atlas code path has been disabled without performance
regressions since 8/3/18, so this deletes it completely from the code
base since it is complex and difficult to manage.

GrTextureStripAtlas, GrDynamicTextureStripAtlas, and
GrDDLTextureStripAtlas completely deleted, everything else is cleaning
up references/dead code using the atlas.
