That breaks the assumption that the work is proportional to loops.
For example, loops = 5 and loops = 7 would result in the same count
if count = loops / 4.

I have text_16_AA_FF -> 8888 (forcing RP) faster than head now on my
laptop. I'm feeling confident that we can make this perform well.
After looking at performance a bit more today, it looks like everything
is within what I'd consider comparable in performance, especially on
ARM. On x86-64 it looks like big bulk blits get a little slower and
small mask blits get a little faster.
Quality looks good, and maybe improved for 565.
There are fewer platform-specific differences now in _lowp, and I think
they're few enough now that we could even consider completing the
unification by folding the 8-bit and float code together. Rename
"div255()" to "rebias()", slap on a few coats of paint...
Guarded for Chrome with SK_JUMPER_LEGACY_LOWP.

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.
