Added a GM that demonstrates the bug. Should draw a blur with
the center masked out, and a circular blurry shape that's
roughly the inverse. On raster, this was already the result.
On GPU, the blurred/eroded layer becomes a subset with an
origin other than (0,0), and that layer was shifted.
I *think* this is the correct fix - we are including 'offset'
in the texture matrices, but that's just based on the crop
rects and adjustments from each filter. We still need to adjust
the texture coords for the subsets themselves.

This is a reland of f065907ccc
3rd time's the charm:
The new analytic gradient shader was sporadically triggering violations of the coverage as alpha
compatibility optimization. Unfortunately, even when using the same device and random seed for the
test, the bots did not always reproduce the error. However, we identified the likely cause of the
violation.
The test requires that all output channels are less than the input alpha, which it uses to validate
whether or not the shader is modulating its values by the input alpha. This test does not pass if
the RGB values are greater than 1. The original version of the analytic gradient shader used half4s
for its scale and bias values. Given the threshold limit for hardstops of 0.00024 (SkNearlyZero),
a very small interval that is not treated as a hardstop can create a scale or bias of over 4000.
This moves into the very imprecise region of 16-bit floats, making it plausible that the gradient
outputs colors greater than 1, due to rounding. The kicker is that the random test generation for
stop locations does not use a uniform distribution, but is instead biased towards the remaining
interval, which increases the likelihood of generating a small interval that is not treated as a
hard stop. We are keeping this behavior since ill-conditioned gradients are useful in testing.

Currently there is no way to trigger this from the public API and it

The "pointy vertex" test was only considering the distance from the
next (outgoing) edge to the previous point. It must also consider the
distance from the previous (incoming) edge to the next point. If
either are less than a quarter pixel, the vertex is considered pointy
and should be removed. (884166)
Also (887103), when an interior region was completely removed due to
boundary simplification, it would leave a degenerate edge consisting
of the same vertex. So avoid introducing a join edge when prev == next.
Bug: 884166, 887103

Provides a reasonably flexible fragment processor that defines another
colorizer implementation for gradients. It can support up to 8
interpolation intervals (which is 16 colors if every stop is a hard stop
or 9 colors if every stop is a smooth transition). It
supports mixtures of hard and smooth stops. It is conditionally compiled

The GrGradientShader controller does not remove the single and dual

Currently it does not employ capabilities detection to determine if the

We don't have anything drawing colors outside sRGB,
but now that we've got SkPaint::setColor4f(), that's easy.
Looks like we have lots of work to do.
Pin GrColor4f floats before converting to unsigned.
Underflowing floats would get pinned to 255 spuriously
instead of to 0. I think this fixes the failing CQ
bot, and the white square problem.
