I think we may be trying to take too many steps at once.
Let's try starting from an API and evolving from there?

Adds support for importing a RECTANGLE texture into Skia via GrTexureProvider::wrapBackendTexture().

Tests read/writing pixels, copySurface, and clear.

Does not add support for texturing from a RECTANGLE texture as the coords will be incorrectly normalized.

4c7040bf8a SampleApp: Make android_install_app and android_launch_app work consistently
Make android_install_app work more consistently:
* App can be "SampleApp" or "VisualBench"

Make android_launch_app work more consistently:
* Parameters to SampleApp are passed correctly
* SampleApp is actually launched

The parameters to "am" need to be quoted, since the command
is run on the device shell.

24a22c7de8 some fuzz hacking
Try to start faster:
 - remove flags dependency
 - print nothing
 - strip unused symbols from the binary on Mac (smaller binary)
 - only create one fuzz object
 - only run one DEF_FUZZ
I am not sure if any of these things mattered, but I thought you may like to look.

Good stuff:
 - make nextU() / nextF() work
 - drop nextURange() / nextFRange() for now
 - add nextB() for a single byte

As you may have guessed, I have figured out how to use afl-fuzz on my laptop.

Syntax to run becomes:
  $ afl-fuzz ... out/Release/fuzz <DEF_FUZZ name> @@

702501ddca Simplify path allocation, clean up resources correctly
Simplify path id allocation in NVPR backend. Instead of using
an AVL tree of path id ranges for the first 65535 ids, use just
a simple stategy of overallocation and "bump index".

Fixes the bug where previously overallocated ids were not deleted.

The advantage is that the implementation is simple and all allocations
go through overallocation, not just the first 65535 of the 1-range
allocations.

Removes the logic where paths were cleared with setting path data to
null instead of deleting the whole path. Now deleted paths are just
deleted normally. These operations should have equivalent performance on
command buffer. Deleting the path should enable the driver to do more
maintainance.

Removes the GLNameAllocator, as it was only used for paths. In order for
it to be used for other IDs, it probably would need to be re-written to
support cleanup and arbitrary ranges. Also, the interface would probably
need to be changed to not requiring the block to be allocated before it
could be managed by the structure.

3a24f45958 Optimized premultiplying swizzles for NEON
Improves decode performance for RGBA encoded PNGs.

Swizzle Time on Nexus 9 (with clang):
SwapPremul 0.44x
Premul     0.44x
Decode Time On Nexus 9 (with clang):
ZeroInit Decodes 0.85x
Regular  Decodes 0.86x

Swizzle Time on Nexus 6P (with clang)
SwapPremul 0.14x
Premul     0.14x
Decode Time On Nexus 6P (with clang):
ZeroInit Decodes 0.93x
Regular  Decodes 0.95x

Notes:
ZeroInit means memory is zero initialized, and we do not write to
memory for large sections of zero pixels (memory use opt for Android).

A profile on Nexus 9 shows that the premultiplication step of PNG
decoding is now ~5% of decode time (down from ~20%).

06d54ad09a Fix SkXfermodeImageFilter GPU fast path for differing sizes.
The GPU fast path was not doing the correct thing for input bitmaps of
differing sizes. This change brings the fast path in line with the
slow path: use the union of foreground and background bounds as bounds,
offset the draw context by the bounds translation, and translate the
foreground and background independently by their respective offsets.

Finally, we add a texture domain for the background fragment
processor, since we may access texels outside its domain.

Note: this adds two new test cases to the xfermodeimagefilter GM, so
those will need to be rebaselined.

This check is useless because it is vulnerable to integer overflow.

Also, I don't think this is the right way to solve the problem
of "too large" images.  For example, many image specs allow images
larger than this, so we should too.

2b12376849 SkTime: Stop using POSIX entensions to time.h for timezone
SkTime::GetDateTime() isn't used anywhere in production, so
change it to return current UTC time, rather than local time.

Also, move code into SkTime out of ports.

A later CL will remove empty files.

368342ccb5 Refactor resize filter to go faster
Part of this CL improves the speed by using dynamic arrays
more effectively.

Part uses SIMD and more concise float expressions for speed.

Some unused code was deleted.

The latter changes are guarded by:

  SK_SUPPORT_LEGACY_BITMAP_FILTER

until this lands and the corresponding layout changes in
chrome can be relanded.

With the legacy flag defined, no Skia or Chrome test results
change. Without the flag defined in Skia, only 0.01% - 0.02%
of the pixels change, and then by (1,1,1) in 8888.

codereview.chromium.org/1583533002 adds the guard to Chrome.

05dcb4c7a9 Optimize SkTileImageFilter in an offset filter when possible.
If the srcRect and dstRect have the same size, tiling will have the
same effect as an offset filter cropped to the intersection of
srcRect and dstRect. So do that instead.

c63a0f8fe5 clamp fixed divide to 32 bits
In SkEdge::setLine, the numerator is a 26.6 fixed number.
SkFixedDiv shifts it up by an additional 16 bits. If the
y interval is small, the result overflows 32 bits.

The code pins in 64 bit space before down-casting the result.

32cdc32522 SkTCopyOnFirstWrite-based SkPaintFilterCanvas API
I find this version preferable because

1) it consolidates the in/out paint args without compromising
efficiency or flexibility

2) relieves overriders from having to set the SkTLazy explicitly
