It's pretty easy to start with sound premultiplied linear floats, pack those to sRGB encoded bytes, then read them back to linear floats and find them not quite premultiplied, with a color channel just a smidge greater than the alpha channel. This can happen basically any time we have different transfer functions for alpha and colors... sRGB being the only one we draw into.
This is an annoying problem with no known good solution. So apply the clamp hammer.
These new calls on SkRasterPipeline should make it impossible to get wrong.

For stages that have {r,g,b,a} and {dr,dg,db,da} versions, name the {r,g,b,a} one "foo" and the {dr,dg,db,da} on "foo_d". The {r,g,b,a} registers are the ones most commonly used and fastest, so they get short ordinary names, and the d-registers are less commonly used and sometimes slower, so they get a suffix.
Some stages naturally opearate on all 8 registers (the xfermodes, accumulate). These names for those look fine and aren't ambiguous.
Also, a bit more re-arrangement in _opts.h.

Image shaders need to do some geometry work before sampling the image colors:
1) determine dst coordinates
2) map back to src coordinates
3) tiling
Feeding (x,y) through as (dr,dg) registers makes step 1) easy, perhaps trivial, while leaving (r,g,b,a) with their usual meanings, "the color", starting with the paint color.
This is easy to tweak into something like (x+0.5, y+0.5, 1) in (dr,dg,db) once this lands. Mostly I just want to get all the uninteresting boilerplate out of the way first.

The refactoring breaks off A2B0 tag support into a separate
subclass of SkColorSpace_Base, while keeping the current
(besides CLUT) functionality in a XYZTRC subclass.
ICC profile loading is now aware of this and creates the A2B0
subclass when SkColorSpace::NewICC() is called on a profile
in need of the A2B0 functionality.
The LabPCSDemo GM loads a .icc profile containing a LAB PCS and
then runs a Lab->XYZ conversion on an image using it so we can
display it and test out the A2B0 SkColorSpace functionality,
sans a/b/m-curves, as well as the Lab->XYZ conversion code.

This is handy now, and becomes necessary with fancier backends:
- most code can't speak the type of AVX pipeline stages,
so indirection's definitely needed there;
- if the pipleine is entirely composed of stock stages,
these enum values become an abstract recipe that can be JITted.

This lets them pick up runtime CPU specializations. Here I've plugged in SSE4.1. This is still one of the N prelude CLs to full 8-at-a-time AVX.
I've moved the union of the stages used by SkRasterPipelineBench and SkRasterPipelineBlitter to SkOpts... they'll all be used by the blitter eventually. Picking up SSE4.1 specialization here (even still just 4 pixels at a time) is a significant speedup, especially to store_srgb(), so much that it's no longer really interesting to compare against the fused-but-default-instruction-set version in the bench. So that's gone now.
That left the SkRasterPipeline unit test as the only other user of the EasyFn simplified interface to SkRasterPipeline. So I converted that back down to the bare-metal interface, and EasyFn and its friends became SkRasterPipeline_opts.h exclusive abbreviations (now called Kernel_Sk4f). This isn't really unexpected: SkXfermode also wanted to build up its own little abstractions, and once you build your own abstraction, the value of an additional EasyFn-like layer plummets to negative.
For simplicity I've left the SkXfermode stages alone, except srcover() which was always part of the blitter. No particular reason except keeping the churn down while I hack. These _can_ be in SkOpts, but don't have to be until we go 8-at-a-time.

In some build configurations (I think, GN, GCC 6, Debug) I get a warning that i is used unintialized. This likely has something to do with GCC correctly seeing that the SkTCast construction there is illegal aliasing, and perhaps thus "doesn't happen". Might be that if the SkTCast gets inlined, it decides its implementation is secretly kosher, and so Release builds don't see this. None of this happens with the GCCs we have on the bots... too old?
Instead use memcpy() here, which is well defined to do what we intended.

We used to step at a 4-pixel stride as long as possible, then run up to 3 times, one pixel at a time. Now replace those 1-at-a-time runs with a single tail stamp if there are 1-3 remaining pixels.
This style is simply more efficient: e.g. we'll blend and lerp once for 3 pixels instead of 3 times. This should make short blits significantly more efficient. It's also more future-oriented... AVX+ on Intel and SVE on ARM support masked loads and stores, so we can do the entire tail in one direct step.
This also makes it possible to re-arrange the code a bit to encapsulate each stage better. I think generally this code reads more clearly than the old code, but YMMV. I've arranged things so you write one function, but it's compiled into two specializations, one for tail=0 (Body) and one for tail>0 (Tail). It's pretty tidy.
For now I've just burned a register to pass around tail. It's 2 bits now, maybe soon 3 with AVX, and capped at 4 for even the craziest new toys, so there are plenty of places we can pack it if we want to get clever.

Today if you use the simple SK_RASTER_STAGE interface to build a pipeline, each stage you add calls into a next stage. The last stage you add calls into a special backstop stage JustReturn that, well, just returns, ending the pipeline.
This adds last(), which cuts that last stage off the pipeline. Instead, the stage you add using last() returns directly, ending the pipeline itself without jumping into JustReturn.
This reduces the overhead of using the pipelined version of SkRasterPipelineBench from ~25% to ~20% on my desktop.
Also, add docs.

We used to build src and dst transfer fn tables
every time a new xform was created with linear
src and dst. Now we don't compute them because
we don't need them.
This will make SkColorSpaceXform a far better
option for any xforms with float or half-float
inputs or outputs, particularly on a small number
of pixels.
This CL also moves SkColorSpaceXform closer to
what I anticipate will be the eventual 'API design'.
I think apply() will want to take a SrcColorType enum
(not created yet because it's not necessary yet) and
a DstColorType enum (still using SkColorType because
there's not yet a reason not to).
Performance changes:
toSRGB 341us -> 366us
to2Dot2 404us -> 403us
toF16 318us -> 304us
There's no reason for toSRGB or to2Dot2 to change.
The refactor seems to have caused the compiler to
order the instructions a little differently...
This is something to come back to if we need to
squeeze more performance out of sRGB. For now,
let's not be held up by something we don't control.
F16 likely improves because we are no longer
(unnecessarily) building the linear tables.
Code size gets a little bigger. Measuring
SkColorSpaceXform size as a percentage of src/ size,
we go from 0.8% to 1.4%.

The recording bench must record some source material into some sort of
display list, and fundamentally cannot separate the timing of the two.
This CL makes it so the source material and display list are of the same type.
So instead of previous:
--nolite: SkRecord-based picture -> SkRecord-based picture
--lite: SkRecord-based picture -> threadsafe SkLiteDL
Now this times
--nolite: SkRecord-based picture -> SkRecord-based picture
--lite: SkLiteDL -> threadsafe SkLiteDL
This makes it easier to profile SkLiteDL and explore both recording and playback overhead hot spots.
The threadsafety is incidental for the source (and doesn't affect playback speed),
but I think it's handy to keep around on the destination to make a more fair comparison.

SkLiteRecorder, a new SkCanvas, fills out SkLiteDL, a new SkDrawable.
This SkDrawable is a display list similar to SkRecord and SkBigPicture / SkRecordedDrawable, but with a few new design points inspired by Android and slimming paint:
1) SkLiteDL is structured as one big contiguous array rather than the two layer structure of SkRecord. This trades away flexibility and large-op-count performance for better data locality for small to medium size pictures.
2) We keep a global freelist of SkLiteDLs, both reusing the SkLiteDL struct itself and its contiguous byte array. This keeps the expected number of mallocs per display list allocation <1 (really, ~0) for cyclical use cases.
These two together mean recording is faster. Measuring against the code we use at head, SkLiteRecorder trends about ~3x faster across various size pictures, matching speed at 0 draws and beating the special-case 1-draw pictures we have today. (I.e. we won't need those special case implementations anymore, because they're slower than this new generic code.) This new strategy records 10 drawRects() in about the same time the old strategy took for 2.
This strategy stays the winner until at least 500 drawRect()s on my laptop, where I stopped checking.
A simpler alternative to freelisting is also possible (but not implemented here), where we allow the client to manually reset() an SkLiteDL for reuse when its refcnt is 1. That's essentially what we're doing with the freelist, except tracking what's available for reuse globally instead of making the client do it.
This code is not fully capable yet, but most of the key design points are there. The internal structure of SkLiteDL is the area I expect to be most volatile (anything involving Op), but its interface and the whole of SkLiteRecorder ought to be just about done.
You can run nanobench --match picture_overhead as a demo. Everything it exercises is fully fleshed out, so what it tests is an apples-to-apples comparison as far as recording costs go. I have not yet compared playback performance.
It should be simple to wrap this into an SkPicture subclass if we want.
I won't start proposing we replace anything old with anything new quite yet until I have more ducks in a row, but this does look pretty promising (similar to the SkRecord over old SkPicture change a couple years ago) and I'd like to land, experiment, iterate, especially with an eye toward Android.

Most visibly this adds a macro SK_RASTER_STAGE that cuts down on the boilerplate of defining a raster pipeline stage function.
Most interestingly, SK_RASTER_STAGE doesn't define a SkRasterPipeline::Fn, but rather a new type EasyFn. This function is always static and inlined, and the details of interacting with the SkRasterPipeline::Stage are taken care of for you: ctx is just passed as a void*, and st->next() is always called. All EasyFns have to do is take care of the meat of the work: update r,g,b, etc. and read and write from their context.
The really neat new feature here is that you can either add EasyFns to a pipeline with the new append() functions, _or_ call them directly yourself. This lets you use the same set of pieces to build either a pipelined version of the function or a custom, fused version. The bench shows this off.
On my desktop, the pipeline version of the bench takes about 25% more time to run than the fused one.
The old approach to creating stages still works fine. I haven't updated SkXfermode.cpp or SkArithmeticMode.cpp because they seemed just as clear using Fn directly as they would have using EasyFn.
If this looks okay to you I will rework the comments in SkRasterPipeline to explain SK_RASTER_STAGE and EasyFn a bit as I've done here in the CL description.
