779125d7bc Cleanup SkGpuDevice factory functions a bit
This CL:
Clumps the proxy creation & device creation parameters together in the factories
Makes the raw SkGpuDevice factory take a "const SkSurfaceProps&"
Makes both the proxy-wrapping & raw factories call the SDC-based factory

639e812d9f Remove usage of sqrt() as an optimization barrier in tests.
In the majority of cases, a uniform is an equally good substitute, and
replacing `sqrt(N)` with `unknownInput` actually makes the test clearer.

8447f13c6d Chop tessellated curves that don't fit in a patch
Previously we would completely disable hardware tessellation for a path
if there was any chance of a curve requiring more segments than
supported by the hardware. This CL updates the tessellators to simply
chop paths until they fit in patches, allowing us to finally draw any
path using hardware tessellation.

6011bbcf48 Fix comma operator support with matrices in Metal.
MetalCodeGen would incorrectly identify `(someMatrix, someScalar)` as a
math operation between `someMatrix` and `someScalar` and attempt to
convert `someScalar` to a matrix. If `someScalar` was a Boolean type,
this would lead to an assertion.

The binary expression is now checked more thoroughly before converting
the scalar into a matrix.

55a63afc5f Make it possible to use the DSL from within the compiler itself
The DSL would not previously function within the compiler, because it
expected to be in charge of everything itself. The compiler and DSL also
disagreed about how to handle some things, such as the DSL not
respecting the compiler's override flags.

This CL moves responsibility for much of the setup process into
DSL::Start(), which the compiler now invokes. DSL::Start() now also
takes a ProgramSettings instead of DSL-specific flags, and the
externalFunctions vector has been moved into ProgramSettings.

f2b08cc9c8 Fix SPIR-V code generation of dead return statements.
If we encounter code like `return 1; return 2;` we need to synthesize a
label, even though the second return statement isn't actually reachable.
This is harmless and satisfies the SPIR-V validator.

Ideally we'd eliminate the dead code entirely, but this case is rare and
isn't likely to cause any problems as-is.

bdf3bb7b5f Add support for componentwise matrix divide in SPIR-V.
All the pieces of the puzzle were already here to support componentwise
addition and subtraction of matrices. Division was just a forgotten gap
in the implementation and is now patched up to match + and -.

NOTE: if you read the SPIR-V output very closely, you may be surprised
that there are fewer FDiv operations than you'd expect from reading the
input SkSL. As it turns out, a preexisting optimization is rewriting
`mat / 4` into `mat * 0.25` (see line 2689), and this rewritten form can
use the dedicated MatrixTimesScalar op. So we only get componentwise
FDivs for the `4 / mat` lines in the source.

c1f6411045 Enable a handful of tests which require ES3.
Previously, these tests were commented out because Runtime Effects could
not compile ES3. More recently, the `enforceES2Restrictions` option flag
was added, which allows these tests to work inside a Runtime Effect.

Most of our commented-out tests can be supported this way; enabling them
a few at a time will make the inevitable debugging simpler when a driver
runs into issues with a test.

ab3e6394a0 Re-enable the nonsquare matrix test.
The mat4x2 portion of the test no longer checks its results, as there
are bugs in the Intel and Radeon GPU drivers that prevent mat4x2s
from being constructed properly.

The SkSL optimizer ends up eliminating the 4x2 matrix entirely because
it is unused by the rest of the code, as well at the 4x4 matrix which is
calculated from the 4x2. At this point, I'm OK with this.

58134e1408 Fix const globals in Metal
We were emitting this at global scope (not in Globals). That would lead
to errors about the variable needing to be in the constant address
space. (You can see the result in ConstArray.metal - the old code was
invalid). Also, we were already making references use _globals, so the
code was double-wrong (or half-right, depending on your perspective).

After the core change, writeVarDeclaration was only used for local
scope, and writeModifiers never used the 'globalContext' parameter.

The removal of finishLine() changed every test output, unfortunately.

6529990763 Fix overdraw from unstable perspective math
There were two issues leading to the corruption seen in the linked
chromium issue.

1. The draw's bounds were calculated based on the quad being clipped
to w>= epsilon, which is what happens when the AA inset/outset is done.
But for non-aa quads, the fillrect and texture ops did no clipping,
assuming that the GPU would be sufficient. However, this can produce
non-aa draws that exceed the calculated bounds, misleading the clip
stack into incorrectly removing the scissor, etc.
2. Precision issues within CropToRect meant some perspective quads'
barycentric coordinates would become degenerate and compute to (0,0,1),
making it appear as if the render target/scissor were contained within
it. This meant we'd turn it into a rectangular clear.

These changes appear to address the corruption on Linux and Windows, but
there are still rendering artifacts from poor aa inset/outset
calculations. These artifacts are at least limited to the clip properly.
A better rendering method that does not rely on line intersections
will address these artifacts, but this CL is a reasonable temporary
mitigation.

4e9d5e2bdf Use Wang's formula for quadratic and cubic point counts
- most of the small diffs are because I moved GrWangsFormula.h out
   of the tessellate/ directory and into the geometry/ directory since
   it's more general than HW tessellation.

The previous implementation was based on the heuristic that the distance
from the true curve to the line segment would be divided by 4 every time
the curve was recursively subdivided. This was a reasonable
approximation if the curve had balanced curvature on both sides of the
split. However, in the case of the new GM's curve, the left half was
already very linear and the right half had much higher curves.

This lead to the approximation reporting fewer points than required.
Theoretically, those few points that weren't utilized by the left half
of the curve could have been made available to the right half, but the
implementation of that would be tricky.

Instead, it now uses Wang's formula to compute the number of points.
Since recursive subdivision leads to linearly spaced samples assuming it
can't stop early, this point count represents a valid upper bound on
what's needed. It also then ensures both left and right halves of a
curve have the point counts they might need w/o updating the
generation implementations. However, since the recursive point
generation exits once each section has reached the error tolerance, in
scenarios where the prior approximation was reasonable, we'll end up
using fewer points than reported by Wang's. Hopefully that means there
is negligible performance regression since we won't be increasing
vertex counts by that much (except where needed for correctness).

Changes the internal function to
  bool computeFastBounds(SkRect* bounds) const;

Subclasses of SkPathEffect must implement this, and can choose to return
false when fast bounds aren't computable.

Provides implementations of computeFastBounds() for path effects

97f85bb7fd Remove SkTextBlobDiffCanvas, use tracking device directly with base SkCanvas
Chromium has been updated to use makeAnalysisCanvas directly and there are
no more references to SkTextBlobDiffCanvas as a type in its code base.

Since the GlyphTrackingDevice extends SkNoPixelsDevice, any SkCanvas that
uses it is effectively a "no-draw" canvas. However, by returning a base
SkCanvas the text tracking now automatically happens in the context of
the base's AutoLayerForImageFilter handling it applies on every draw. This
means that drawing a text blob with an image filter that modifies the
transform state will now be analyzed in that context automatically
(simplifying code in chrome after this lands).

Another behavioral change is that all non-text draws will still go through
the base SkCanvas' virtuals and invoke the device function. Since it's an
SkNoPixelsDevice, it'll still be a no-op, it just happens a little later.
This won't really impact performance because oop-r already inspects their
operations and only plays back text and transform related ones to the
analysis canvas, so we shouldn't really see non-text draws being invoked
anyways.

c9125aa8f3 Reland "Better first-class shader & color filter support in runtime effects"
This is a reland of adadb95a9f
... adds a temporary workaround for some Android framework code.

Original change's description:
> Better first-class shader & color filter support in runtime effects
>
> This does a few things, because they're all intertwined:
>
> 1) SkRuntimeEffect's API now includes details about children (which Skia
>    stage was declared, not just the name). The factories verify that the
>    declared types in the SkSL match up with the C++ types being passed.
>    Today, we still only support adding children of the same type, so the
>    checks are simple. Once we allow mixing types, we'll be testing the
>    declared type against the actual C++ type supplied for each slot.
> 2) Adds sample variants that supply the input color to the child. This
>    is now the only way to invoke a colorFilter child. Internally, we
>    support passing a color when invoking a child shader, but I'm not
>    exposing that. It's not clearly part of the semantics of the Skia
>    pipeline, and is almost never useful. It also exposes users to
>    several inconsistencies (skbug.com/11942).
> 3) Because of #2, it's possible that we can't compute a reusable program
>    to filter individual colors. In that case, we don't set the constant
>    output for constant input optimization, and filterColor4f falls back
>    to the slower base-class implementation.

daa9b8e4d9 Add mapRect function and RectToRect constructor to SkM44
The SkM44::RectToRect function matches the semantics of
SkMatrix::RectToRect(kFill_ScaleToFit). No other ScaleToFit variants are
ported over to SkM44.

skottie uses some instances of kCenter_ScaleToFit so that functionality
may need to be added in the future (in SkM44 or in skottie). There are
no current usages of the kStart and kEnd_ScaleToFit semantics.

The SkM44::mapRect() function is implemented to correspond to the
SkMatrix::mapRect() that returns the mapped rect (instead of modifying a
pointer) and always has ApplyPerspectiveClip::kYes. This was chosen to
keep its behavior simple and because perspective clipping is almost
always the right thing to do. In the new implementation there is no
longer a performance cliff to worry about (see below). For the timebeing
mapRect is hidden behind SkMatrixPriv::MapRect().

Performance:
I added benchmarks for mapRect() on SkM44 and SkMatrix that use the same
matrices to get a fair comparison on their different specializations.
SkMatrix has a very efficient mapRect when it's scale+translate or
simpler, then another impl. for affine matrices, and then falls back to
SkPath clipping when there's perspective. On the other hand, SkM44 only
has 2 modes: affine and perspective.

On my desktop, with a Ryzen 9 3900X, here are the times for 100,000 calls
to mapRect for different types of matrices:
                         SkMatrix    SkM44
scale+translate           0.35 ms    0.42 ms
rotate                    1.70 ms    0.42 ms
perspective              63.90 ms    0.66 ms
clipped-perspective      138.0 ms    0.96 ms

To summarize, the SkM44::mapRect is almost as fast as the s+t specialization
in SkMatrix, but for all non-perspective matrices. For perspective matrices
it's only 2x slower than that specialization when no vertices are clipped,
and still almost 2x faster than the affine specialization when vertices are
clipped (and 100x faster than falling back to SkPath).

Given that, there's the open question of whether or not keeping an affine
specialization is worth it for SkM44's code size.

371f6e18e5 Refactored SkSL function creation and error handling
This breaks up the giant IRGenerator::convertFunction method into more-
manageable chunks, moves the functionality into FunctionDeclaration,
and funnels the DSL through it so it receives the same error checking.

b6cce2d4c7 don't draw strings that have no glyphs
This string had several characters which resulted in zero
glyphs. Having zero glyphs bypassed the buffer sizing code,
and continued to process the glyph run list assuming it had
7 runs because the buffer sizing code also clears the run list.
This caused the code to process runs from a previous SkTextBlob,
which was already deleted.

If the there are no glyphs, call the buffer sizing code to
set up all the invariants. Exit if there are no runs produced.

830c69ca66 Implement operator== and != for Metal structs and arrays.
GLSL/SkSL assumes that == and != on struct/array types should work.
We need to emit equality and inequality operators whenever we find code
that compares a struct or array.

Structs and arrays can be arbitrarily nested, and either type can
contain a matrix. All of these things need custom equality operators in
Metal. Therefore, we need to recursively generate comparison operators
when any of these types are encountered.

For arrays we get lucky, and we can cover all possible array types and
sizes with a single templated operator== method. Structs and matrices
have no such luck, and are generated separately on a per-type basis.

For each of these types, operator== is implemented as an equality check
on each field, and operator!= is implemented in terms of operator==.
Equality and inequality are always emitted together. (Previously, matrix
equality and inequality were emitted and implemented independently, but
this is no longer the case.)

65d7ab2c07 Loosen ES3 restrictions in Runtime Effects for debugging.
This CL adds a RuntimeEffect option flag which skips over the various
`strictES2Mode` checks sprinkled throughout IR generation.

Runtime Effects still won't allow a lot of ES3 things (the Pipeline
stage will reject unsupported statement types, SkVM doesn't support most
non-ES2 constructs, etc). However, this change will give us the ability
to test many more features involving arrays and structs that previously
were off-limits due to ES2 restrictions, and will shore up some
legitimate gaps in our testing. This is a useful starting point to allow
for improved test coverage.

In some cases this can be fairly significant, e.g. RectBlurEffect has
a global with the expression
    abs(rect.x) > 16000 || abs(rect.y) > 16000 ||
    abs(rect.z) > 16000 || abs(rect.w) > 16000

d6e1e0fb46 Use macros for sk_Caps again.
This undoes the change from http://review.skia.org/400541 and reworks
sk_Caps to use macros, exactly like the existing CPPCodeGenerator.

This compromise is necessary for when-expressions. Specifically, when-
expressions must be valid when parsed *either* as SkSL or as C++. We
want to support when-expressions that reference sk_Caps, like:

    layout(when=!sk_Caps.floatIs32Bits)

The macro approach allows this when-expression to work.

ec871bf353 Fix global variables which call built-in functions.
When emitting a built-in function call, we need to honor the `fCPPMode`
state. Previously we were rewriting the call into a DSL call even in C++
mode.

We also now spell out Fract's complete namespace, to avoid a name
collision with MacTypes.h:

4d5711192a Reland "Runtime effects: Detect passthrough sample calls automatically"
As explained, this is *very* conservative. It only works when the child
is sampled from within main, and using a direct reference to the coords
parameter. If that parameter is ever modified (even after being used),
the optimization doesn't happen. For most cases, this is fine.

Reland changes the logic in GrSkSLFP slightly, to avoid turning all
samples into pass-through when a child is sampled with both pass-through
and explicit coordinates.

b9fc6e45c2 Support 'layout(when)' expressions in DSL C++.
This required some changes to how we name variables in DSL.
When-expressions are designed to expect a local C++ variable with the
same name as the layout key. This constraint means our DSLVar variables
CANNOT have the same name as the layout key. Now, all DSL variables are
given a prefix. We try to keep the code tidy by using just a leading
underscore as the prefix, where it's safe to do so. (The C++ naming
rules put some underscore-names out of bounds, but underscore followed
by a lowercase letter is safe.)

08771b00eb Add DSLVar::swap method.
This gives DSLVar the ability to be set up after initial construction.
To do this, we create a plain empty Var, then swap it with the actual
Var we want afterwards. This allows DSL to support Vars which are
`uniform half4` in some cases and `const half4` (or entirely unused) in
other cases.

This technique was adapted from similar code in Ethan's parser CL.

48f106501c Reland "Stop using copying SkPath::Iter for convexity and contains checks"
This reverts commit 29c06bc82a.

Reason for revert: Convexicator::BySign did not handle count <= 3, which
it previously never encountered because a path with leading moveTos
would actually turn into a sequence of moveTo+close by the forceClose
SkPath::Iter so it'd never actually skip anything.

I updated the code so that BySign checks for count <= 3 after we've
skipped leading moveTos. This means computeConvexity's logic can get
a little simpler, just checking isFinite(), calling into BySign, and
then going into the second pass. Previously, it skipped the first pass
if pointCount <= 3 (using the pointCount before leading moveTos were
skipped).

Lastly, I removed SkPathPriv::IsConvex. It was the other user of
BySign but it was only used in PathTest. I figured it's best to have
a single source of convexity definition rather than having two code
paths that both need to implement the same two-pass behavior.

93250090c2 Reland "remove fAllocators from GrOpsTask"
This is a reland of f00d6a8efd

This change is significantly different from the original.

The lifetime of GrArenas on the GrSurfaceFillContext is from
first GrOpsTask creation to the completion of the first call
to GrOpsTask::onExecute. The overall lifetime of the GrArenas
is from first GrOpsTask creation until the last dtor of the
GrOpsTask.

There are checks in the GrArena to make sure that nothing is
allocated after it is removed from the GrSurfaceFillContext.

c412688798 Reland "Implement statements and expressions in DSL C++ code generator."
This is a reland of 16cbfb41df

Tests now rely on `shaderDerivativeSupport` and `integerSupport` as
proxies to indicate ES3 support. The SwitchStatement test has been
adjusted to hopefully confuse fewer compilers.
