394d414452 Implement SkHighContrastFilter
This is a color filter to apply several contrast adjustments for users
with low vision, including inverting the colors (in either RGB or HSL
space), applying gamma correction, converting to grayscale, and increasing
the contrast.

a950a86d22 Fix rounding error with tiled bitmap draws
We were snapping the top-left of the destination rectangle to integers,
but using the original (fractional) size. This led to us losing rows or
columns of pixels at the first tile boundary.

Also added a GM that demonstrates the bug (now renders correctly).

0bd699e497 Add a GM for SkShadowUtils and fix a few issues.
1) Transform the path center to device space before computing the shadow offset.

2) Modulate the shadow color by the color filter's output color.

3) Make the scale of path points in the spot tessellator be relative to the path centroid.

4) Clamp the shadow alphas at 1.

e7a364d435 GrTessellator: fix artifact with exactly-1-px-wide edges.
When path features are exactly a pixel wide, the extruded inner edges
can become collinear and then be removed, since their winding is
zero. We need these edges to be preserved through triangulation,
otherwise opaque portions of the geometry can become transparent.

Since the simplify() pass can handle zero-winding edges just fine, the
the fix is to simply not remove them.

In addition, this changes refactors out disconnect() from all the calls
to remove_edge_above()/remove_edge_below(). It also renames the remaining
function erase_edge() (since it's now unconditional).

Add a new test to a new "thinconcavepaths" GM.

84014f03a9 Respect SkColorSpace in SkPNGImageEncoder
This only changes behavior when the input SkBitmap/SkPixmap is
tagged with a non-null SkColorSpace.  Android tags their bitmaps
as sRGB when linear blending is enabled.  So this only changes
behavior in Android when linear blending is turned on.
*If linear blending is turned on, this will do a color correct
 encode (which is the desired behavior).
*If linear blending is turned off, this will do a legacy encode.

TODO: Add support for F16.
TODO: Add color space support to WEBP.
TODO: Tag encoded images with ICC profiles (when it makes sense).

6e74412a9c Create .gni files for samples, tests, gms, and benches.
Calling Python to find all these files is convenient, but error-prone.  It's easy to forget to call GN again when adding a file.  Each of these calls to Python also adds ~50ms to the run time of gn gen, which is small but adds up.

On my desktop, gn gen drops from 600ms to 150ms, noticeably faster.

This leaves one call to find.py for generating skia.h for fiddle.  We're not quite sure how to automate that process to happen entirely inside the :skia.h action while maintaining correct dependencies, so I'm leaving it for now.
