I originally thought that there was no harm in reading or skipping
zero lines after we have already reached the end of the image.
However, once we reach the end of the image, onFinish() is
automatically called. Performing a read or a skip after
the call to onFinish() is invalid and will cause onFinish()
to be called a second time (which is also invalid).
Seems like the code requires good behavior and the test is
wrong.

This experiment replaces the label used in the aaxfermodes gm with
aliased text generated from paths common to all platforms.
Since there is no way today to generate all dm output from trybots,
this will be checked in to confirm that this strategy provides simpler
output across devices.
This does not introduce a new public interface; instead, dm uses
a extern backdoor to install the SkTypeface::CreateFromName
handler.

kScanline_Subset_Mode decodes the image in subsets using a
scanline decoder.
The number of subsets can be specified by changing the constant divisor.
The number of subsets is equal to divisor*divisor.

Previously it was hard to tell that DrawFn took an SkCanvas* and returned an Error. Now it's clear from the type.

If so, let's do it this way so it works for all source types and doesn't need
to be chosen at compile time.

Will use this to test the other CL that adds small SkPicture implementations.
Not quite sure why patch_primitive doesn't draw the same in 8888 and sp-8888, but everything else does, so I'm not going to let that hold me back for now.

This requires we remove NVPR from the default set of configs, as we only find
out at runtime that it's not available. All the other defaults will either be
compiled in and supported, or not compiled in and non-fatally skipped as
unknown configs.

Motivation: I want to switch back to single-page output by default for
direct comparison to raster backends in Gold.
I can still test the multi-page option via a command-line switch.

We may want to enable swizzles to 565
for images that are encoded in a format
similar to 565, however, we do not want
to take images that decode naturally to
kN32 and then convert them to 565.
***Enable swizzles to kIndex_8. For images
encoded in a color table format, we suggest
that they be decoded to kIndex_8. When we
decode, we only allow conversion to kIndex_8
if it matches the suggested color type (except
wbmp which seems good as is).
***Modify dm to test images that decode to
kIndex_8.

I'm going to start hacking on SkCanvas a bit to allow a fast reset method,
and I want to have some testing checking me.

The file is expected to contain a list of strings. If the hash for
any result is in this file, don't write an image for it.

Duplicate code from the HWUI backends for DM and nanobench
moves into a single place, saving a hundred lines or more of
cut-and-paste.
There's some indication that this increases the incidence of
SkCanvas "Unable to find device for layer." warnings, but no
clear degradation in test results.
