d1701ba884 IWYU for gms starting with 'a'.
There is still a bit of manual mucking about with iwyu output to get
things nice, but the checker seems to be doing ok and the process is now
a bit easier. Will see how it goes.

This also pointed out the amount of code behind ifdefs should be
minimized by using the build system and 'constexpr if' when possible.

f460eeec99 Use linear metrics flag for linear metrics.
Now that no one is using the linear metrics flag directly, change the
meaning from 'no-hinting and subpixel positioning at an odd size when
measuring and just no-hinting when drawing' to meaning 'use linear
metrics'.

This also changes the font hosts to no longer use subpixel positioning
as a proxy for this value. This fixes outstanding bugs in Chromium about
getting the right metrics for hinted fonts.

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

c725e8f7ea Make SkShaper's GN setup more DLL friendly
Similar to the Skottie refactor that just landed, this avoids having an
empty component when shaper is disabled (which turns into a DLL with no
sources, and a missing DllMain). I think this pattern of having modules
expose the same components as empty groups is simpler (and also fixes
the fact that only two of N references in top-level BUILD.gn were
guarded). Also, no one is using the define?

ca9465688f Make Skottie's GN setup more DLL friendly
Skottie doesn't currently build with is_component_build=true. Trying to
build a DLL with skia_enable_skottie=false failed, because we ended up
with a component("skottie") that had no sources. That led to fallback
linker behavior, but no DllMain.

To solve this, and simplify things, move the skia_enable_skottie checks
to the outer scope, and simply replace all the referenced components
with empty groups when it's not enabled. Also fix some fm code that was
assuming it was always enabled.

b161a7d965 [skottie] Fix gradient ramp interaction with non-atomic draws
Currently, shader effects are applied via layers for non-atomic draw fragments.

This is incorrect, as shaders on layer paints are ignored.

Update to always propagate the shader to leaf node paints.

866e262a21 [skottie] Fix gradient ramp for non-solid layers
Two issues:

  1) Empirically (per AE's model), only solid layers transform the effect space.
     All other layer types implement their effects ignoring the layer xform.

  2) Due to the effect deferral mechanism in sksg, shader effects are
     sometimes applied with a different transform than intended.

To address #1, tweak the layer builder logic to attach the effects
before/after the transform node, depending on the layer type.

For #2, track the CTM active when the shader effect is attached and undo
any intervening transformations via a local matrix when the shader is
actually applied to SkPaint.

9a9e723f02 [skottie] Add support for (non-standard) v-centered text
Introduce a Skottie JSON extension for controlling vertical text
alignment ("sk_vj"), with a single public value for now: 1 (centered).

Refactor SkottieShaper to handle vertical adjustments based on a VAlign
enum:

  kTop         - the topmost line is ascent-aligned with the box top
                 (AE text-box behavior)
  kTopBaseline - the topmost line is baseline-aligned with the top box
                 (AE text-point behavior)
  kCenter      - the text center is aligned with the box center
                 ("sk_vj": 1, Skottie extension)

Also externalize the vertical adjustment as a text blob offset (instead
of baking into blob glyph offsets).

4428f2c39f Remove SkScalarSinCos
This differed from the separate versions in that it snapped to zero.
It was also strictly worse than calling the two separate versions.
Most clients don't need the snapping, so just call the two existing
functions. For clients that need the snapping, call new variants of
each that do snap.

3d846c98ca [skottie] Initial gradient ramp effect support
Implement gradient ramp using SG shader effects.

A couple of quirks:

- since the gradient type (linear/radial) is animatiable (?!),
  update sksg::ShaderEffect to allow resetting the shader

- gradient ramp doesn't have an assigned/stable JSON effect type,
  but the data is present; introduce a name-based effect lookup method
  (used as a fallback when the type is not recognized)

fb4bce8322 [sksg] Refactor gradient implementation
Currently, gradients are PaintNode subclasses - which limits their
applicability to leaf DAG nodes.

In order to support generalized gradient/shader effects:

  * introduce a new Shader base class
  * refactor gradients as Shader subclasses
  * introduce ShaderPaint (to support current Gradient-as-paint use)
  * introduce ShaderEffect (to support future Gradient-as-effect use)

Tangentially:

  * rename SkSGPaintNode.h -> SkSGPaint.h
  * consolidate sksg::Color into SkSGPaint.h
