Bug: b/163595585
In a WebP image, it is possible to combine animation with an EXIF
orientation. While SkAndroidCodec attempts to handle orientation itself
by decoding into temporary memory and then drawing through a matrix,
this doesn't work directly when compositing a P-frame into a prior
frame. SkAnimatedImage already uses an SkMatrix to handle cropping and
scaling, so update that matrix to include the orientation.
Make SkAnimatedImage a friend of SkAndroidCodec. This allows the former
to have the same ExifOrientationBehavior specified by the latter, and to
recreate the latter so it does not try to handle the orientation itself.
Clip SkAnimatedImage to its bounds. Android's AnimatedImageDrawable
performs its own clip, but this makes a crop rect work for other
clients.
Update getCurrentFrame to take cropping, scaling, and orientation into
account. This method is used by CanvasKit, which does not use cropping
or scaling, but will now properly orient an animation with an EXIF
orientation.
Add a GM that exercises the various combinations of ways SkAnimatedImage
can be used:
- via newPictureSnapshot (as in Android) versus getCurrentFrame
- scaling down to a dimension that can be output from the
SkAndroidCodec, versus up, which SkAnimatedImage scales
- with a crop rect
- with a post processor

The 'pts' coordinates should be transformed by the view matrix. We could
instead apply the inverse src rotation to ptsRot when determining the
perpendicular and parallel scales, but this is valid and straight
forward.
When determining the device segment lengths in onPrepare, we do need to
transform the ptsRot by fSrcInvRot (which includes the view matrix),
instead of just the view matrix.
This fixes the linked chromium bug, which drew a wider stroked dash
because on a perfect vertical, the rotation to a canonical x-axis
geometry would end up swapping perpendicular and parallel scale factors.

This removes the kMixed type of SkSL::SampleMatrix. All analysis of FP
sampling due to parent-child relationships is tracked in flags on
GrFragmentProcessor now.
The sample strategy is tracked as follows:
- An FP marks itself as using the local coordinate builtin directly (automatically done for .fp code based on reference to sk_TransformedCoords2D[0]).
- This state propagates up the parent towards the root, marking FPs as using coordinates indirectly. We stop the propagation when we hit a parent FP that explicitly samples the child because it becomes the source of the child's coordinates.
- If that parent references its local coordinates directly, that kicks off its own upwards propagation.
- Being sampled explicitly propagates down to all children, and effectively disables vertex-shader evaluation of transforms.
- A variable matrix automatically marks this flag as well, since it's essentially a shortcut to (matrix expression) * coords.
- The matrix type also propagates down, but right now that's only for whether or not there's perspective.
- This doesn't affect FS coord evaluation since each FP applies its action independently.
- But for VS-promoted transforms, the child's varying may inherit perspective (or other more general matrix types) from the parent and switch from a float2 to a float3.
- A SampleMatrix no longer tracks a base or owner, GrFragmentProcessor exposes its parent FP. An FP's sample matrix is always owned by its immediate parent.
- This means that you can have a hierarchy from root to leaf like: [uniform, none, none, uses local coords], and that leaf will have a SampleMatrix of kNone type. However, because of parent tracking, the coordinate generation can walk up to the root and detect the proper transform expression it needs to produce, and automatically de-duplicate across children.
Currently, all FP's that are explicitly sampled have a signature of (color, float2 coord). FP's that don't use local coords, or whose coords are promoted to a varying have a signature of (color).
- In this case, the shader builder either updates args.fLocalCoords to point to the varying directly, or adds a float2 local to the function body that includes the perspective divide.
GrFragmentProcessor automatically pretends it has an identity coord transform if the FP is marked as referencing the local coord builtin. This allows these FPs to still be processed as part of GrGLSLGeometryProcessor::collectTransforms, but removes the need for FP implementations to declare an identity GrCoordTransform.
- To test this theory, GrTextureEffect and GrSkSLFP no longer have coord transforms explicitly.
- Later CLs can trivially remove them from a lot of the other effects.
- The coord generation should not change because it detects in both cases that the coord transform matrices were identity.
GrGLSLGeometryProcessor's collectTransforms and emitTransformCode has been completely overhauled to recurse up an FP's parent pointers and collect the expressions that affect the result. It de-duplicates expressions between siblings, and is able to produce a single varying for the base local coord (either when there are no intervening transforms, or the root FP needs an explicit coordinate to start off with).
This also adds the fp_sample_chaining GM from Brian, with a few more configurations to fill out the cells.

These functions can be performed generically using SkRasterPipeline
or skcms. Further, the reason we used a function pointer anyway was
so that we could call the same function on each row separately. But
libwebp's API doesn't let us do a single row at a time anyway.
Simplify this method by using readPixels when necessary and
skipping conversion entirely when possible.
Add support for encoding from unpremul 4444. It is simpler to support
it, and it's not obvious why we didn't support it before.
Keep the behavior of not supporting A8, and apply the same to the
other alpha-only formats. Note that we could support encoding such an
image to alpha, r=0, g=0, b=0, but I'd rather leave adding that
feature to a separate change, which enables it for all encoders (and
accounts for the internal use of PNGs as a round-trip for
kAlpha_8_SkColorType).
Add GMs to test the newly supported SkColorTypes.

The goal of the verifier framework is to enable opt-in checks of the
images produced by individual GMs. The basis of verification will be
comparing the rendered output of a GM against a source-of-truth image,
such as one generated by the CPU backend.
In the short term this can enable coarse-grained sanity checks for a
subset of GMs to catch e.g. egregious rendering bugs. In the longer term
this can provide an SkQP-style suite of tests that can be run across
many/all GMs to provide a vote of confidence in the rendering
correctness of new devices.

The goal of the verifier framework is to enable opt-in checks of the
images produced by individual GMs. The basis of verification will be
comparing the rendered output of a GM against a source-of-truth image,
such as one generated by the CPU backend.
In the short term this can enable coarse-grained sanity checks for a
subset of GMs to catch e.g. egregious rendering bugs. In the longer term
this can provide an SkQP-style suite of tests that can be run across
many/all GMs to provide a vote of confidence in the rendering
correctness of new devices.

Rename to texel_subset.
Test different x/y wrap modes.
Use a real image that is non-square.
Add dividers to group MakeTexelSubset() with Make() reference draw.
Use a smaller image, fewer matrices, and only one subset rect to
make room for the additional mode combinations.

Today's shader hash changes if the unordered set of {r,g,b,a} values we
produce changes, but is not sensitive to simple order changes like
sampling RGBA vs BGRA.
Folding in a hash of each value's ID in order will fix this.
This has been difficult to track down (thread-local caches),
so I've added a GM that reliably reproduces the bug.

Modeled on https://codepen.io/adamdupuis/pen/qLYzqB, this GM creates a
cube of rectangles with the camera at the center. It animates the FOV
since the original chrome issue was most visible when resizing the page
(which then updated the fov of the perspective css transform).
This draws correctly with the raster backend. There are two issues it
causes with Ganesh:
1. The input coordinates of some of the cube faces have 0 or negative ws.
- When negative, the current bounds code does not perform clipping and
just uses the mirrored point, which leads to misleading bounds.
- When 0, the current bounds code produces infinities, and then GrOpsTask
discards the op with non-finite bounds.
2. The anti-aliasing code also ignores w <= 0, and so all of its screen
space math is incorrect.
This causes a mix of completely discarded draws and distorted draws on the
GPU backend.

This completes pushing through the new virtual didConcat44() to our
subclasses, and introduces didScale() for future optimizations. We
don't call didScale yet, until external subclasses are also updated.
