Convert existing log messages to the new machinery.

cbcff385c1 Have pathkit use libpathkit.a for faster builds
Of note, it is very important for the -DSK_RELEASE/-DSK_DEBUG
to match between libskia.a and the WASM bindings, otherwise
things like SKDEBUGCODE are sometimes compiled in and sometimes
not, which can cause headaches like sizeof() mismatching between
.cpp files and .h files.

97b150e73b [skottie] External font loader tweaks
More general ResourceProvider font loading API:

1) font name argument
2) invoked unconditionally (regardless of whether an URL is present)

This provides more font control to the embedder.

217056c048 [CanvasKit] Implement some basic Canvas/Surface things.
drawText is having issues in a release build.  Skottie sometimes
asserts in debug mode. This possibly has something to do with
memory alignment - like https://skia-review.googlesource.com/c/skia/+/155980
helped fix.

Patchset 9 shows off integrating Skia drawing to
an HTML canvas using Ganesh.

To see it locally, set up https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
and then set $EMSDK to be that directory.  Then run

   make clean
   make local-example

and navigate to http://localhost:8000/skia-wasm/example.html

Patchset 20 shows off Skottie animating directly to a Canvas.

a900ad5400 Make fallback font iterator in shaper cache fallback.
Most of the time when doing fallback there is a simple ping pong between

a cache of one. This greatly speeds up the example layout.

In the future more work will be done on caching.

ab706d85e0 [skottie] SkTArray begone
SkTArray is not a good choice for tigh allocations:

  - its minimum allocation count is 8
  - reserve(sz) doesn't adjust capacity to the exact value, but padds
    the same way as normal growth (max(sz, 8, 50%))
  - no shrink_to_fit() function to trim unneeded capacity

Since keyframed properties with a small number of frames are quite
common in Lottie, this adds significant heap overhead.

Switch to std::vector(), reserve() to the estimated frame count and
shrink_to_fit() when done parsing.

12e3df13cf [skottie] Harden interpolation checks for shapes
The "closed" shape property cannot be interpolated -- so ensure we catch
different values in interpolation pre-checks.

679d05c48a [sksg] Simplify ScopedRenderContext
ScopedRenderContext tries really hard to avoid unnecessary RenderContext
initializations.

This is most likely unneeded because

  a) the structure is quite lightweight

and

  b) all ScopedRenderContext instantiation sites imediately call setters
     which require a writable context (assuming no-op args are uncommon)

Let's get rid of that over-engineered gunk.

73154babe5 [skottie] Avoid UB while parsing 1-based indices
Current impl can underflow int due to unchecked arithmetic.

Add a Parse<size_t> specialization and convert call sites which use
inline arithmetic.  Underflowing unsigned types should be well defined
and caught in later tests.

b2c4ea6219 Move Views into Sample and Viewer.
What is left of the SkView system is used only by samples or viewer.
As a result, move it out of the Skia source tree and re-organize so it
is a bit easier to understand and use more shared code.

Move samplecode/ClockFaceView.cpp to samplecode/SampleTextEffects.cpp,
sice that's what's actually in it.

Move SkAnimTimer.h to tools/timer, since it's actually shared between gm
and samples.

e12a090a63 make some textblob builders private for now
Move SkTextBlobBuilder::allocRunText* to private: for the time
being, to reduce the documented interface footprint.

No code is deleted; the functions may be restored when a
client is ready to call them.

Also, add SkTextBlob::MakeFromString to complement
SkTextBlob::MakeFromText.

c0132ffa64 [skottie] Optimize opacity layerization
- plumb a RenderContext RenderNode::render() argument to track pending
    opacity

  - defer opacity application until we can determine whether a layer is
    required (group with multiple children) or the opacity can be pushed
    onto the draw paint (for single/atomic draws)
