This is useful because it allows the variables to be declared as `const`
when they are trivial values like `half4(1)`. This enables the constant
folder to simplify or eliminate them. In most cases, this is only a
small benefit, as you'd expect a competent GPU driver to do the same.
However, Mali-400 can benefit significantly from optimizing away the
multiplication against a constant half4(1) coverage in Porter-Duff.
Mali-400 performance is back to normal: http://screen/3cDxdaGkYE8oBcS

- Added "Dump Shaders" button; this writes the shaders to disk in the
`/resources/sksl` directory. This will allow us to more easily check
real-world shader code generation, instead of synthetic examples.
- Renamed "Load" and "Save" to "View" and "Apply Changes," to clarify
that they are not about files on disk. (Otherwise they seemed
confusing when placed next to a Dump Shaders button.)
Also, fixed a bug which would prevent a new deferred action from being

Try to uncover races by running parallel replicas.
The default --race 0 should keep FM working as before, but now with
--race ≥2 we'll actively try to race replicas, syncing between tests.
--race 1 is almost pointless, just changing the thread tests run on but
without any interesting concurrency.
Rearrange a bit how fm_driver decides what flags to pass to which
invocations of FM, so individual runs can easily override defaults (e.g.
--nativeFonts overriding the usual --nonativeFonts). Use that here to
set --race 0 for unit tests; many unit tests are not reentrant.

The 'lang' was never stored or used, so this makes no current practical

that it could be emitted as a 'Lang' override in the 'ActualText' when
generating a PDF. However, due to the way 'ActualText' is generally used
this would be impractical. If there is ever a desire to mark up sections
of the PDF with a specific language it would be better handled in a
different way.

Create an actual hairline path instead of a filled path. Allow metric

glyph has an outline and a hairline is needed. This also fixes glyph
bounds issues with path based glyphs drawn with hairlines.
Stroke+Fill is not handled very well, but is currently being deprecated
and so given less weight. It works, but is somewhat arbitrary.
Also add more paint overrides to Viewer.
Note that this only adds hairline handling for backup purposes. The code
in SkStrikeSpec::ShouldDrawAsPath which causes most harline glyphs to be
drawn directly from paths is not changed.

This change treats all slides as being in units of points (not pixels).
Window dimensions are communicated to slides in terms of points. This
allows slides which use the window dimensions for scaling to remain in
the same unit space as the gms. Allowing thh slides to also know the
actual pixel dimensions is left for later (this may be wanted when
testing proper selection of bitmap resources).
This also splits the backing scale from the zoom factor. The backing
scale is allowed to be toggled by the user. This allows for easy
reproduction at nominal size. When the backing scale is turned off the
points and the pixels are the same size. Slides which use the window
dimensions for scaling have the backing scale moved from the Viewer
transform to the window dimensions which are reported in pixels
(which are equal to points) when the backing scale is turned off.
