22534f2098 Expose sk_FragCoord for runtime effects
This is needed for the inline dither effect to use device coordinates
instead of local coords for dithering.

The builtin is not "in float4" because that trips up the runtime effect
assertions about what types of in variables are allowed.

5e6b3cd259 Store float value for settings in SkSL v2
If you used 'in float foo' in a runtime effect it would always have the
value cast to an int. I don't think we saw this in .fp files because
the cpp generation handled those values directly (if I remember correctly)

Just uses a union of float and int, differentiated by fKind, so that it
compiles in standalone mode (vs. using SkFloat2Bits, etc.).

Also updated to add a unit test.

d9bde07f1e Add SkRuntimeShaderBuilder, clean up SkRuntimeEffect API a bit
Utility class for getting named access to uniforms and children of an
SkRuntimeEffect (also functions as an example of using the
SkRuntimeEffect public API).

Moved several internal SkRuntimeEffect functions to private, and added
findInput/findChild helpers.

5f6b41e6d8 Runtime effects: Detect calls to undefined functions
Previously, the CPU backend would catch this later (ByteCodeGenerator),
and the GPU backend would assert in expandFormatArgs (out-of-range
function index).

6f5e94089e Clamp GrSkSLFP output to valid premul
Added this as an option to GrSaturateProcessor (also renamed it to
be more generic and end with FragmentProcessor).

Added a tweak to the unit test to check the new behavior.
(Raster was already doing the clamp).

504032e575 SkRuntimeEffect: Fix 'in' variables in CPU backend
We were never calling specialize() to bake in the values of ins,
so do that. Add uniformSize() to get the size of just the uniform
values. (The interpreter asserts that the size of the uniforms
being passed in matches the expected size from the ByteCode,
so these need to match up).

Added a unit test that uses both 'in' and 'uniform'.

- 'in' variables can't be arrays (applies to all SkSL)
- 'in' and 'uniform' variables are restricted to a fixed

088913a63b Start adding unit tests of SkRuntimeEffect
- Change SkRuntimeEffect::Make so *it* can fail, and returns
  [Effect, ErrorText].
- Initial tests just test for expected failure conditions.
  Next steps are to add tests for effects that should work,
  and to validate results on CPU and GPU.
