f01a6c3663970ccd6e1882e76a887e0fda467b77 18-Jun-2014 scroggo <scroggo@google.com> In Android framework, make tools depend on jsoncpp

Always build the tools with JSON, but either build our own
or use the system's.

Rename skia_build_json_writer to skia_use_system_jsoncpp,
since we now always build with JSON.

Remove SK_BUILD_JSON_WRITER, which was only there so
we could build without JSON it in the framework.

ifdef out code that won't build where we don't have jsoncpp.

Include ctype instead of string.h for tolower.

99589af4e333422639d7e873207dd323fdd6e808 10-Dec-2013 commit-bot@chromium.org <commit-bot@chromium.org@2bbb7eff-a529-9590-31e7-b0007b416f81> Add support for reading a directory of images with --expectations (-r).

DM writes out its images in a hierarchy that's a little different than GM,
so this can't read GM's output. But it can read its own, written with -w.

Example usage:
$ out/Release/dm -w /tmp/baseline
$ out/Release/dm -r /tmp/baseline -w /tmp/new
(and optionally)
$ mkdir /tmp/diff; out/Release/skdiff /tmp/baseline /tmp/new /tmp/diff

GM's IndividualImageExpectationsSource and Expectations are a little too eager
about decoding and hashing the expected images, so I took the opportunity to
add DM::Expectations that mostly replaces skiagm::ExpectationsSource and
skiagm::Expectations in DM. It mainly exists to move the image decoding and
comparison off the main thread, which would otherwise be a major speed
bottleneck.

I tried to use skiagm code where possible. One notable place where I differed
is in this new feature. When -r is a directory of images, DM does no hashing.
It considerably faster to read the expected file into an SkBitmap and do a
byte-for-byte comparison than to hash the two bitmaps and check those.

The example usage above isn't quite working 100% yet. Expectations on some GMs
fail, even with no binary change. I haven't pinned down whether this is due to
- a bug in DM
- flaky GMs
- unthreadsafe GMs
- flaky image decoding
- unthreadsafe image decoding
- something else
but I intend to. Leon, Derek and I have suspected PNG decoding isn't
threadsafe, but are as yet unable to prove it.

I also seem to be able to cause malloc to fail on my laptop if I run too many
configs at once, though I never seem to be using more than ~1G of RAM. Will
track that down too.
