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 adds an error variable that keeps track of the total distance from
the simplified line, and includes it when determining if we should
keep the next point. Using a sum of line distance is just a heuristic
but seems to address the current case of over simplification while
allowing us to keep a greedy strategy.

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.

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.

don't call didScale yet, until external subclasses are also updated.

This doesn't resolve all the problems here but does substantially improve the situation. In particular, if the device-space stroke is greater than 1 in one axis and less than 1 in the other, the smaller side will still appear darker than expected.

The matrices we're using can produce very slightly out of range color
channels. This gives surprising results when in shader blending is used
for color burn and color dodge. After this change we clamp the RGB
values to 0..1 before applying premul.
Adds a GM modeled on a blink layout test that shows the problem using
SkImageMakeFromYUVAPixmaps.

It's not drawing anything earthshattering, but it does act as an easy
way to exercise some interesting code paths in SkVMBlitter, here first
program caching based on shader program and not shader identity.
With today's shader caching patches, this makes 2 calls to
skvm::Builder::done(), JITing the program, while if you patched this in
at head you'd see 3. I'd like it to get down to 1 by converting paint
colors to color shaders.

Without the changes to GrShape and GrAAConvexPathRenderer, this new GM
would not draw the red circle at the center when using Ganesh. Raster
drew the red circle. The difference came about because they checked
convexity after transforming by the view matrix, and Ganesh checked
before.
With this particular path construction and the very large scale factor
on the CTM, the convexity calculator in local space computed small
enough edge vectors that it thought the contour backtracked on itself
instead of winding in a consistent direction.
The GrAAConvexPathRenderer would claim it could draw the convex path,
but later when actually preparing to draw, it would do nothing if it
turned out the convex path didn't have a direction. This CL updates it
so that the convex path renderer's canDraw() function matches what it
is actually able to draw.
There is the separate issue of the convexity/direction checking
precision.
