e50167091c Move Sk3Perspective and Sk3Lookat into SkM44
Sk3Perspective -> SkM44::Perspective
Sk3LookAt -> SkM44::LookAt

Also adds some SK_API tags to the SkV[2,3,4] structs. Also fixes
linkage issues around Sk3Perspective/LookAt by moving them into the
exported SkM44 (if we don't like them as SkM44 factories, will just need
to add SK_API tags to old Sk3Perspective/Lookat directly).

91292e9482 Runtime Effects: Support 'uniform shader' (vs. 'in shader')
The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

7571f9e490 Replace 'typedef xxxxx INHERITED' with 'using INHERITED = xxxx;'.
Mechanically updated via Xcode "Replace Regular Expression":

  typedef (.*) INHERITED;
    -->
  using INHERITED = $1;

The ClangTidy approach generated an even larger CL which would have
required a significant amount of hand-tweaking to be usable.

767f444feb SkRuntimeEffect SkSL has a new signature for main()
There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.

The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).

For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.

Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

a4b9169fb6 Remove 'in' variables from SkRuntimeEffect
Runtime effects previously allowed two kinds of global input variables:
'in' variables could be bool, int, or float. 'uniform' could be float,
vector, or matrix. Uniform variables worked like you'd expect, but 'in'
variables were baked into the program statically. There was a large
amount of machinery to make this work, and it meant that 'in' variables
needed to have values before we could make decisions about program
caching, and before we could catch some errors. It was also essentially
syntactic sugar over the client just inserting the value into their SkSL
as a string. Finally: No one was using the feature.

To simplify the mental model, and make the API much more predictable,
this CL removes 'in' variables entirely. We no longer need to
"specialize" runtime effect programs, which means we can catch more
errors up front (those not detected until optimization). All of the API
that referred to "inputs" (the previous term that unified 'in' and
'uniform') now just refers to "uniforms".

f59a961dc9 Add layout(marker) to SkSL
Allows for uniforms to be automatically populated with
marked canvas matrices:

SkSL:
  layout (marker=localToWorld) uniform float4x4 localToWorldMatrix;

C++:
  canvas->concat(...);
  canvas->markCTM("localToWorld");
  canvas->concat(...);
  canvas->drawFoo(...);

Any runtime effects created with that SkSL will have their
localToWorldMatrix uniform filled in with the CTM, ignoring
any transformation that happened before/above the markCTM
call. The marker needs to be a sequence of alphanumeric or
underscore characters, and match the string used in markCTM.

The marker can also be of the form "normals(<string>)", in
which case the uniform will be filled in with the transpose
of the inverse of the upper-left 3x3 portion of the CTM
identified by <string>. This is helpful for transforming
normal vectors, as is often done in lighting.

808f021b51 Improve error handling in SkSL ByteCode
- Allow for $floatLiteral and $intLiteral when determining type
  categories. These could slip into the IR, leading to asserts.
- We weren't propagating the source text in specialize(), so errors in
  the ByteCodeGenerator would actually assert about a missing fSource.
  It's held by unique_ptr on Program, so we wastefully clone the
  string, but we don't have that many specializations yet, so not too
  bad?

ea7711d4a8 Tweak pointlight3d sample to work in Raster backend
- Once we add all the missing intrinsics, the locally defined ones
  can go away.
- Having the default interpreter vector width match the raster pipeline
  is a huge perf win.

8c2ccc07ba use real normal-map texture
transpose(inverse(localToWorld)) does not seem to be working, so skipping
it for now.

ee3216d8f8 Use SkSL to do point-light shading
- misc fixes to utilities
- hit-testing for 3D scenes (simple version)

Had to manually inform the shader of the local-to-world matrix.
Should try making that automatic in the future.

Note: due to bug in interpreter, point-light sample can't run in raster
(yet).

b18e74dcbd Expose camera matrix in SkCanvas
3 new getters:
- localToWorld
- localToCamera
- localToDevice (same as total-matrix)

The current tracking minimizes overhead, by using a computed inverse to
produce the localToWorld/Camera. This can be change as needed in the
future (more precision, but more memory/overhead), but for now is
sufficient to try out the new APIs.
