I think we can replace a lot of legacy code with an SkRasterPipeline
backend that works in 8-bit and stays interlaced. Think of this as a
"lowerp" replacement for lowp.
I'm having some trouble getting ARMv8 working.
ARMv7 should be fine, but I want to turn it on separately from x86.
I haven't looked at 32-bit x86 yet, but that's also on the todo list.
Open questions to follow up on:
- is it better to fold every multiply back down to 8-bit
(as seen here), or to allow intermediates to accumulate
in 16-bit and divide by 255 when done/needed?
- is it better pass tightly packed 8-bit vectors between stages (as
seen here), or to keep the 8-bit values unpacked in 16-bit lanes?
- should we make V wider than 1 register?
GMs look good. All diffs invisible and plausibly due to the 15->8 bit
precision drop. A quick bench run showed this running in about 0.75x
the time of the existing lowp backend.

There is now one tracing flag: 'trace'.
- 'debugf' installs the SkDebugf tracer.
- 'atrace' installs the Android ATrace tracer.
- Any other value is interpreted as a filename, and
produces a JSON file for chrome://tracing.
All three modes work in DM, nanobench, and Viewer.

Remove #defines that lived in gn_to_bp.py and
android_framework_defines.gni. These have been moved into a new file
in Android, SkUserConfigManual.h, in https://googleplex-android-review.git.corp.google.com/#/c/2519600/
Update gn_to_bp.py to include SkUserConfigManual.h, so it will still
result in using the same #defines.
Lately, we've found it difficult to guard changes behind a flag. e.g.
a change to drawing causes a CTS failure in Android, so we have to do
the following:
- put the change behind a flag, and add it to gn_to_bp.py or
android_framework_defines.gni
- generate new images on Android (by running CTS with external/skia
modified to not define the flag)
- create a CL in CTS that uses the new images
- land a CL in Skia that stops defining the flag
- when the Skia change lands, wait for the auto-roller to create a CL
that includes the change, stop the auto-roller, add the topic to the CTS
CL so the two can land at the same time
- land both Android changes (with TreeHugger)
- restart the Android auto-roller
With SkUserConfigManual.h (which lives in Android), the process will
be similar to Chromium:
- land a CL in Android's external/skia that defines a flag e.g.
SK_SUPPORT_LEGACY_FEATURE. Land without TreeHugger because it isn't used
in Skia and does not do anything
- land a change in Skia that changes behavior unless
SK_SUPPORT_LEGACY_FEATURE is defined. This will safely go through the
Android roll and not change any behavior for Android
- create two Android CLs - one in CTS to use the new images, and one in
external/skia to delete SK_SUPPORT_LEGACY_FEATURE. Set them to the same
topic and land them with TreeHugger
In the new process, there is no need to mess with the Android roll.
A downside to the new process is that we cannot test the android
framework defines without checking in to Android. But given how much
we've progressed in automating Android testing, this is fine.

than calling new to create that block of memory, which may crash
when we run out of memory, call malloc, and return null if malloc
fails.
Add a common base class for Mask and Standard BMP codecs. This class
handles allocating and freeing the buffer.
