The extra generality of having a std::function is for MDB reordering. In the current MDB reordering world there is one pass through the surfaceProxies at creation time and a second pass after flush to create the usage intervals.

All of the published coefficients assume math is being done on bytes, and
that 128 is the encoding of 0 (in the biased Cb and Cr values). When
sampling an A8 texture, though, GPUs typically decode as byte/255. Thus,
128 ends up slightly larger than 0.5. To fix this, just adjust the bias
terms to be scaled by 128/255, rather than 0.5.
I also changed some of the other coefficients to be higher precision,
based on the values in ITU-T T.871.
This originally surfaced as a Chromium bug where an all-black JPG decoded
to (1/255, 0, 1/255) on GPU. I've added a GM that encodes a color cube to
JPG, then draws from the encoded data. GPU and CPU (libjpeg) still
disagree in many cases, but the newer version performs much better
(diffing gl and 8888 configs):
Previously: 95.2% of pixels differ, max diff of 2, avg diff of 1
Now : 65.4% of pixels differ, max diff of 1, avg diff of 0

This brings the optimization in blink's FEComposit::MapRect() [1]
into skia.
Previously for these classes we used the default SkImageFilter::
onFilterBounds() which returns the union of the bounds of input filters.
However, this was not optimized if some input filters don't contribute
to the output. When we switch blink SPv2 paint invalidation from using
blink's FilterOperations to cc/skia's filter classes, the non-
optimization caused over-raster-invalidations.
Now override SkImageFilter::onFilterBounds() in these classes to make
their filterBounds() return the same results as the blink counterparts.
Also fix a bug of SkArithmeticImageFilter when k4 is non-zero by
overriding affectsTransparentBlack() to return true in the case, so
that we will use the crop as the final bounds.

This fixes an Android rendering bug where radial gradients were being used
for "clipping" (via DstIn blend mode). The gradient stops were placed at
(0, 0.999, 1), which caused our table quantization to drop the last stop.
kThree_ColorType now means "0, any t, 1". The old (special-case)
kThree_ColorType is now called kSymmetricThree_ColorType.

This script does the following:
* Downloads the repo tool.
* Inits and checks out the bare-minimum required Android checkout.
* Sets the required git config options in external/skia.
* Cherry-picks the specified Skia patch.
* Modifies the change subject to append a "Test:" line required for presubmits.
* Uploads the Skia change to Android's Gerrit instance.
After the change is uploaded to Android, developers can trigger TH and download binaries (if required) after runs complete.
The script re-uses the workdir when it is run again. To start from a clean slate delete the workdir.
Timings:
* ~1m15s when using an empty/non-existent workdir for the first time.
* ~15s when using a workdir previously populated by the script.
