The two bugs are/were:
The old loop to draw the hoisted layers included the saveLayer call which caused double application of the layer's paint (This is the +1 change).
The hoisted layer is intended to be drawn in device coordinates. The old code was drawing it in the coordinate space of the saveLayer thus it was misplaced (This is the setMatrix change).

DM's striking off into its own JSON world. This gets strawman implementations
in place for writing and reading a JSON file mapping test name to hashes.
For what it's worth, I basically want to change _all_ these pieces,
- MD5 is slow and we can replace it with something faster,
- JSON schema needs room to grow more data,
- it'd be nice to hash once instead of twice when reading and writing,
- this code wants lots of refactoring,
but this gives us a starting platform to work on these bits at our leisure.
E.x. file for now:

SkTaskGroup is like SkThreadPool except the threads stay in
one global pool. Each SkTaskGroup itself is tiny (4 bytes)
and its wait() method applies only to tasks add()ed to that
instance, not the whole thread pool.
This means we don't need to bring up new thread pools when
tests themselves want to use multithreading (e.g. pathops,
quilt). We just create a new SkTaskGroup and wait for that
to complete. This should be more efficient, and allow us
to expand where we use threads to really latency sensitive
places. E.g. we can probably now use these in nanobench
for CPU .skp rendering.
Now that all threads are sharing the same pool, I think we
can remove most of the custom mechanism pathops tests use
to control threading. They'll just ride on the global pool
with all other tests now.
This (temporarily?) removes the GPU multithreading feature
from DM, which we don't use.
On my desktop, DM runs a little faster (57s -> 55s) in
Debug, and a lot faster in Release (36s -> 24s). The bots
show speedups of similar proportions, cutting more than a
minute off the N4/Release and Win7/Debug runtimes.
