1e6c5b8dee Add a "preferredInternalSampleCount" cap
This new cap tells Ganesh how many samples to use when performing
internal draws with MSAA or mixed samples. The default is always 4x,
but the client can change that with
GrContextOptions::fPreferredInternalMSAASampleCount.

Also adds a command line flag to viewer to control
fPreferredInternalMSAASampleCount.

5bee390667 Viewer: Fixes for shader editing in ANGLE

- Flush cache when switching backends. Fixes issues between (eg) GL
  and ANGLE where shader caps are different.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

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.

No-Presubmit: true

cbc33b8e35 Add SkSL viewing/editing to viewer
Still only works with the GL backend. For other backends,
need to add similar logic to the shader caching, and some
extra checks in Viewer to force the SkSL flag on.

But in GL, this lets you toggle the checkbox and see the
SkSL / GLSL at will (and edit in either form).

0b8bb88cbb GLSL editing in Viewer
When in GL backend, adds a "Shaders" section to the debug menu.
"Load" scrapes all of the vertex and fragment shaders being used,
then displays them. They can be edited, and "Save" pushes the
results.

Note: It is trivial to trigger an assert by saving a shader that
doesn't compile. I'd like to make the program builder more robust
in a follow-up CL, to fall back to the "real" SkSL, not draw, or
something along those lines.

f55fa0d0cf Make SkPaintFilterCanvas paints no longer COW.
The two existing external users of SkPaintFilterCanvas always end up
making a copy of the paint when the canvas is in use. As a result, the
extra overhead of doing COW is being wasted. In general, it seems easier
for users to optimize by simply not using the filter canvas when it
won't be making any changes. Also, no users are using the 'Type'.

After users are updated to this new API, the old onFilter can be
removed.

a8fbeba6cb Add a cap to allow coverage counting or not
We don't want to just disable the "ccpr" path renderer anymore (or
whatever it should be called), because we are adding an MSAA
implementation. This new cap will eventually tell ccpr whether it can
use coverage counting, or if it should just use the MSAA impl.

110c703b5d Move fontmgr_bounds label setting to checkbox.
The fontmgr_bounds gm has an option to show the name of the font and the
glyph ids of the glyphs with extreme bounds. This was previously done
with a command line flag label_fontmgr_bounds. However, this information
is generally only useful in the viewer application, so change this to a
control.

This also adds bool field handling in viewer.

the up and down keys can still be used to get away from and back to no
zoom. The new zoom allows for a much larger range of zoom, allowing more
issues to be seen.

SkCanvas::flush is problematic and we wish to deprecate it. As a first step, this CL begins to remove Skia's internal usage of it.

Ideally clients would use SkSurface::flush and/or GrContext::flush.

74826c81bd Restore old Viewer setup order.
The backend needs to be set up before setting the current slide because
some slides require the backend resolution to set their size. We'll
check to see if a slide is set before drawing instead.

Also adds a null slide to be drawn when no slides are loaded.

804f17e35b [Viewer] Set the current slide first before attaching the fBackendType to fWindow.
If call attach() first, Viewer::onBackendCreated() calls Window::show().
When WM_PAINT occurs, Viewer::drawSlide() is called, where a crash occurs using an uninitialized fCurrentSlide.

7c979f52c3 Experimental Particle System
This adds a new "Particles" slide to viewer, that allows
editing, loading, and saving particle effects. All of the
particle system code is in modules/particles.

There are many rough edges and some not-yet-finished changes
to generalize the model[1]. A rough overview:

- SkReflected.h implements a lightweight reflection system
  for classes derived from SkReflected. Adding a new class
  involves deriving from SkReflected, adding a macro to the
  class declaration, and implementing visitFields(), which
  simply calls a virtual on an SkFieldVisitor for each field.
  Currently, emitters and affectors use this mechanism.

- SkParticleSerialization.h demonstrates two useful field
  visitors - for serializing to and from JSON. The driver
  code that uses those is directly in ParticlesSlide.

- SkParticleData.h and SkCurve.h define a variety of helper
  types for talking about particles, both for parameterizing
  individual values, and communicating about the state of a
  particle among the effect, affectors, and emitters.

- SkParticleEffect.h defines the static data definition of
  an effect (SkParticleEffectParams), as well as a running
  instance of an effect (SkParticleEffect). The effect has
  simple update() and draw() methods.

- ParticlesSlide.cpp adds a third field visitor to generate
  GUIs for interactively editing the running effect.

---

1: The critical change I'd like to make is to remove all
special case behavior over time and at spawn (setting sprite
frames, size over time, color over time, etc...). Integration
is the only fixed function behavior. Everything else is driven
by two lists of affectors. One is applied at spawn time, using
the effect's lifetime to evaluate curves. This allows spawning
particles with different colors as the effect ages out, for
example. The second list is applied every frame to update
existing particles, and is driven by the particle's lifetime.
This allows particles to change color after being spawned, for
example.

With a small set of affectors using a single expressive curve
primitive (keyframed list of cubic curve segments), we can
have affectors that update color, size, velocity, position,
sprite frame, etc., and implement many complex behaviors.
