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.

The overarching goal here is for our "gm" and "render_pictures" tools to handle
image expectations/actuals in the same way, sharing the same code, so their
results can be processed through a single pipeline.
By adding an Expectation class within tools/image_expectations.h, similar to
the Expectations class in gm/gm_expectations.h, we get one step closer to
that goal.

--key describes the type of run (describes the line on the chart), --properties
describes the run itself (describes the dot on the chart).
We'll pass --properties gitHash <git hash> build_number <build number> --key
... to nanobench from the bots.
And... delete a whole lot of dead code.
Example: nanobench --properties gitHash foo build_number 1234 --key bar baz
{
"build_number" : "1234",
"gitHash" : "foo",
"key" : {
"bar" : "baz"
},
"results" : {
....

Extreme implicit quartic equations solve to roots that are different
enough that they appear to have failed. In this case, fall back on
binary searching to find an intersection.
Relax the condition when this happens; don't give up just because the
computed implicit root points aren't remotely the same.

Remove unused headers
replace dynamic memory wstream with null wstream.
Use SkAutoTDelete when appropriate.
Replace PdfRenderer class with short function: pdf_to_stream.
Collapse render_pdf, process_input, tool_main_core functions
Split out process_input_files function.
Don't crash when no arguments given.
print out max rss on each skp.
prettier output
