There is a common piece of code which finds and positions glyphs and is used in four places. Some places copied the code, some places added callbacks. Here is a list of code:
SkDraw::drawPosText
GrAtlasTextContext::internalDrawBMPPosText
GrAtlasTextContext::internalDrawDFPosText
SkXPSDevice::drawPosText
This only extracts the code from SkDraw::drawPosText. I would like to use it in the other three places. I think this code is performance neutral.

- remove float -> int conversion, keeping float -> byte
- remove support for doubles
I was thinking of specializing Sk8f for AVX. This will help keep the complexity down.
This may cause minor diffs in radial gradients: toBytes() rounds where castTrunc() truncated. But I don't see any diffs in Gold.

This doesn't do anything yet beyond print out a message in Debug mode,
but it's a start. Those messages should match the -SSE4-, -AVX-, or -AVX2- in
the Test-...-Debug-Trybots below. The Release ones are just running by accident.
So far they look right to me.

SkPx is like Sk4px, except each platform implementation of SkPx can declare
a different sweet spot of N pixels, with extra loads and stores to handle the
ragged edge of 0<n<N pixels.
In this case, _sse's sweet spot remains 4 pixels. _neon jumps up to 8 so
we can now use NEON's transposing loads and stores, and _none is just 1.
This makes operations involving alpha considerably more efficient on NEON,
as alpha is its own distinct 8x8 bit plane that's easy to toss around.
This incorporates a few other improvements I've been wanting:
- no requirement that we're dealing with SkPMColor. SkColor works too.
- no anonymous namespace hack to differentiate implementations.
Codegen and perf look good on Clang/x86-64 and GCC/ARMv7.
The NEON code looks very similar to the old NEON code, as intended.
No .skp or GM diffs on my laptop. Don't expect any.
I intend this to replace Sk4px. Plan after landing:
- port SkXfermode_opts.h
- port Color32 in SkBlitRow_D32.cpp (and move to SkBlitRow_opts.h like other
SkOpts code)
- delete all Sk4px-related code
- clean up evolutionary dead ends in SkNx (Sk16b, Sk16h, Sk4i, Sk4d, etc.)
leaving Sk2f, Sk4f (and Sk2s, Sk4s).
- find a machine with AVX2 to work on, write SkPx_avx2.h handling 8 pixels
at a time.
In the end we'll have Sk4f for float pixels, SkPx for fixed-point pixels.

The main thrust of this CL is to remove knowledge of the atlas' backing texture from the BatchPlot. It also reduces the API surface of the BatchPlot and shrinks the amount of fields in the BatchAtlas.

we are replacing).
Additionally, the static Create() function does not
need to repeat the name BitmapRegionDecoder.

Quits requiring EXT_raster_multisample and
NV_sample_mask_override_coverage for mixed samples support. This will
allow platforms without those latter extensions (i.e. Chrome) to still
use mixed samples for path rendering. Also moves the mixed samples cap
out of shader caps, since it no longer denotes shader functionality.

This is the GPU equivalent of https://codereview.chromium.org/1415653003/.
It requires passing down the bounds of the crop rect (srcBounds), and
turning the blur 3-patch optimization in convolve_gaussian() into a 5-patch:
clear above and below srcBounds, blur with bounds checks inside left and
right rects, blur without bounds checks in middle rect.
Note: this change causes minor pixels diffs in the
imagefilterscropexpand GM: for odd crop positions relative to the
dstBounds, we are now correctly resampling at an even pixel boundary.
