When timing individual tiles in bench_pictures, keep a timer running
across all repeats, and then take the average. The former method of
timing each iteration separately runs into precision errors on some
platforms.
Running on my Mac Pro with OSX 10.8, the cmsecs for the new method
and the old method are roughly the same when checking the CPU time.
When checking the wall time, the old method often gives me 0ms,
while the new method gives me a larger value. I don't think this
can be entirely attributed to rounding though, since on occasion I
see the old method showing a short time period (.05 - .15ms) while
the new method shows .15ms higher (which is in range for the
difference I'm seeing for other tiles where the old method reports
0ms).
Some other changes:
PictureRenderer::resetState now takes a boolean parameter. If called
with false, it will only do a flush, while if called with true, it
will also call finish.
resetState is now called with true everywhere except in between
iterations of drawing the same tile (when timing individual tiles).
render_pictures_main no longer calls resetState directly, since it
already calls end, which calls resetState.

Chrome uses this flag for recording to skpicture in order to improve performance.
Therefore, skai benchmarks should run with this flag enabled, and we need
gm and render_pictures test coverage to validate it. In gm, the vanilla
SkPicture test step will still run without the flag to ensure that case still gets test
coverage, while the SkPicture test steps that use rtree and tileGrid will now run with
the flag enabled.

1) flag to verify PNGs produced by render_picture that produce the same pixels
as simple renderer.
2) flag to write one single image (in tile we write individual tiles) - this
will help running skdiff also
3) flag to clone the picture before rendering

In TiledPictureRenderer and CopyTilesRenderer, do a postTranslate so
the translate is not affected by the scale factor.
Likewise, use clipRegion for tiled renderer so it will be
unaffected by the scale factor.
Respect the viewport for record, playbackCreation, and pipe renderers.

Builds on https://codereview.appspot.com/6718046/ by mtklein.
Previously, each iteration of drawing a picture started new threads to draw the picture. Since each thread is using thread local storage for the font cache, this means that each iteration had to start with an empty font cache.
The newly added MultiCorePictureRenderer, separated from TiledPictureRenderer, now starts the drawing threads at the beginning of the test using an SkThreadPool, and keeps them alive through all iterations, so the font cache can be reused.
For now, I have removed the pipe version of the threaded renderer.
Updated bench_pictures_main and render_pictures_main to use the new
renderer, and to unref a renderer before early exit.

When doing tiled rendering in multiple threads, clone fPicture,
rather than the blank fPictureClones. Also fix a precedence
problem so we get the correct rectangle.
In render_pictures_main, call PictureRenderer::setup().

Since the passed in picture may represent an image which is too large
to be represented on the GPU, never create such a large canvas. Instead,
after drawing to each tile, create a file showing just that tile.

Also includes some code cleanup and code sharing.
Allow setting the number of threads on the command line.
Rename ThreadSafePipeController::playback to ::draw, to be the same
as SkPicture so DrawTileToCanvas can take a template parameter.
Disallow multithreading with GPU turned on.
Display help information with improper tiled arguments.

Move SkBenchLogger into separate files and make bench_pictures use it.
Remove sk_tools::print_msg, since SkBenchLogger is now used instead.
Combine picture_benchmark with bench_pictures, since that is the
only project that uses it.
Refactor the aggregator for bench timer data into its own class and
make bench_pictures use it.
Consolidate the various virtual PictureBenchmark::run functions
into one for reuse.

Further, the picture is also stored in the PictureRenderer.
The main gain of all of this is that we will not have to change how the device in more than one place when we end up adding different devices.
