c38cce63b3 make SkColorSpace_New real
Some interesting things are starting to fall out already,
like the fact that I needed to add a gamma_dst stage to
be able to draw into gamma-transfer-fn destinations.

I've also had to pass an SkAlphaType through to the linearize
functions so that they can maintain premul invariants.  I'm not
sure this is actually a good idea... if you can, please double-
check my logic at SkRasterPipeline.cpp:128?

If it's correct logic, I'm going to need to do it all over the place.
But I imagine you don't do this and somehow get away with it.

Fix core.gni to use not use Assembler for none cpu.

Right now, there are no outputs because we aren't compiling
dm or nanobench.  However, this still compiles the skia
library and creates two executables, so it's a good canary
for a real WASM build.

Additional note: the two executables in question don't draw
anything to the screen via GL, which is still not possible with
Skia+WASM.

9b2f69b0aa grand unifried lowp stages
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.

ad8a43f769 DeferredDisplayList API proposal
Chrome would like to perform cpu-side preprocessing for gpu draws in parallel. 
They do not want to go through a picture (since they have their own display list format).


The general idea is that we add a new SkDeferredDisplayListRecorder class to
perform all of Ganesh's cpu-side preprocessing ahead of time and in parallel.

The SkDDLRecorder operates like SkPictureRecorder. The user can get an SkCanvas
from the SkDDLRecorder and feed it draw operations. Once finished, the user
calls 'detach' to get an SkDeferredDisplayList. All the work up to and 
including the 'detach' call can be done in parallel and will not touch
the GPU. To actually get pixels the client must call SkSurface::draw(SkDDL)
on an SkSurface that is "compatible" with the surface characterization
initially given to the SkDDLMaker.

The surface characterization contains the minimum amount of information Ganesh needs 
to know about the ultimate destination in order to perform its cpu-side work
(i.e., caps, width, height, config).

it's actually much more natural to work de-interlaced there.  Lots
of room to follow up.

df60e369a8 New analytic AA scan converter using delta (I call it DAA for now)
DAA is:

1. Much simpler than AAA.
   SkScan_AAAPath.cpp is about 1700 lines.
   SkScan_DAAPath.cpp is about 300 lines.
   The whole DAA CL is only about 800 lines.

2. Much faster than AAA for complicated paths.
   The speedup applies to GL backend (including ccpr)!
   Here's the frame time of 'SampleApp --slide Chart' on macbook pro:
     AAA-raster: 33ms
     DAA-raster: 21ms
     AAA-gl:     30ms
     DAA-gl:     20ms
     AAA-ccpr:   18ms
     DAA-ccpr:   12ms
   My linux desktop doesn't have SSE3 so the speedup is smaller
   (~25% for Chart). I believe that DAA is so fast that I can enable
   it for any paths (AAA is not enabled by default for complicated
   paths because it is slow; hence our older supersampling scan
   converter is used for stroking on Chart for AAA-xxx config.)

3. The SkCoverageDelta is suitable for threaded backend with
   out-of-order concurrent scan conversion as commented in the source
   code. Maybe we can also just send deltas to GPU.

4. Similar to most analytic path renderers, the quality is on the best
   ground-truth level, unless there are intersections within a pixel.
   The intersections look good to my eyes although theoretically that
   could be arbitrary far from the ground truth (see my AAA slides).

5. For simple paths, such as circle, triangle, rrect, etc., DAA is
   slower than AAA. But DAA is faster than our older supersampling
   scan converter in most cases. As those simple paths usually don't
   constitute the bottleneck of a picture (skp or svg), I strongly
   recommend use DAA.

6. DAA also heavily favors blitMask so it may work quite well with
   SkRasterPipeline and SkRasterPipelineBlitter.

Finally, please check https://skia-review.googlesource.com/c/22420/
which accelerate DAA by specializing blitCoverageDeltas for
SkARGB32_Blitter and SkARGB32_Black_Blitter. It brings a little(<5%)
speedup. But I couldn't figure out how to reduce the duplicate code
so I don't intend to land it.

0fddb2d7c1 Retry cleaning up SkLinearBitmapPipeline.
This is mostly dead code.

In order to make it truly dead, we need to opt drawing unpremul images
into SkRasterPipelineBlitter.  They had been handled by
SkLinearBitmapPipeline, but can't be draw by SkBitmapProcLegacyShader.

Drawing unpremul images is tested by the GM all_variants_8888, which
gave us trouble last time around (serialize-8888 drew right, 8888 wrong)
but now draws fine.  I think this was probably also the root of the
revert, drawing some unpremul image in Chrome's tests somewhere.
