PDF 32000-1:2008 Section 9.6.4 FontSubsets
"The tag shall consist of six uppercase letters" "followed by a plus
sign" "different subsets in the same PDF file shall have different
tags."
Since Skia always tries to subset fonts in PDF, always prepend a subset
tag.

SkFontStyle needs to be updated to take scalar weight and width, and
separate slant and italic into separate scalar values. Since there are
currently issues with serialization of SkFontStyle, start with the
serialization and deserialization before moving these changes up into
SkFontStyle and its users itself.

These aren't allowed on push constants (it's a validation error now), so
we at least catch it in the SPIRV generator and emit an error. Fixed two

Skia relies on the existence of FT_COLR_COMPOSITE_PLUS, FT_ClipBox, and
FT_Get_Color_Glyph_ClipBox for COLRv1 support. However, these were not
available in the released FreeType 2.11.0 headers since the
specification later changed to require these. In addition, since 2.11.0,
FT_PaintRadialGradient changed the types of two of its members and the
Skia code must depend on this change.
Unrelated, the FT_STATIC_CAST macro was added after these changes. So
undefine TT_SUPPORT_COLRV1 if FreeType is less than 2.11.1 unless
FT_STATIC_CAST is defined.

https://skia-review.googlesource.com/c/buildbot/+/473357
Review Tips:
- Ignore any changes to .h or .cpp files. Those have been
pulled out into their own CLs.
- Start with bazel/macros.bzl.
- Read the CL with the generation code, if you haven't already.
- Look at third_party/file_map_for_bazel.json.
- See experimental/bazel_test for an idea of how a cc_binary
would be made.
- Spot check one or two of the BUILD.bazel files.
This CL generates the "atomic" rules for src/, include/ and
modules/skshaper, as a starting point.
`bazel build --config clang //include/...` works
`bazel build --config clang //src/...` starts compiling,
(which verifies that the BUILD.bazel files are all valid),
but runs into errors because not all third_party deps have
been resolved, and there are some files missing from the
toolchain still (e.g. EGL headers).

Things have evolved since these were last updated. In particular, we no
longer emit binding and set decorations for each individual uniform.
Backends that rely on that (SPIRV, Metal), generate SkSL that has all
the uniforms grouped in a buffer. GLSL emits the uniforms with no layout
qualifiers. SPIRV supported this already (and automatically applied the
default binding/set to the implicitly created uniform buffer). Metal
*almost* supported this - it handled the uniform buffer correctly, but
didn't apply the default binding to any un-decorated samplers.

GrGLGpu:

Previously, we would avoid emitting redundant trace_vars by checking to
see if the slot is being assigned to the exact same Var.ID. However,
this had the potential to eliminate useful trace_vars:
- At the start of execution, slots all contain 0. Code which explicitly
assigned a zero into a slot would not be shown in a trace. (So things
like `color = half4(0,1,0,1)` would only emit traces for color.ga.)
- A function call's parameter slots are reused every time it is called,
so calling a function twice would only emit traces for the parameters
that aren't the same Val.ID as the previous call.
- A VarDeclaration inside a loop reuses its slot each time through the
loop, even though conceptually it's a "new" variable.
We now track a slot's "written-to" status. At the start of execution,
no slots have been "written-to". These slots will always emit a
trace_var opcode (fixing the first issue). Also, issuing a function
call or declaring a variable will reset the "written-to" status of the
associated slots (fixing the second and third issues).
When the debugger is not in use, the written-to field is unused.

We now canonicalize commutative operations by ordering their value IDs.
The lower-numbered value ID is always placed first into a commutative
instruction. In other words, this instruction:
bit_and result, v7, v5
Would be silently converted to this:
bit_and result, v5, v7
This will allow these two logically-equivalent instructions to be
deduplicated:
bit_and result, v7, v5
bit_and result, v5, v7
Of course, deduplicating these ops can unlock additional free CSE/DCE.
