Chrome GPU Assisted Decode of VP8 and VP9 greater than 1080p content

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Enable Intel BDW platforms for GPU assisted decode of VP8 and VP9 content
2.  Play YouTube Content greater than 1080p resolution

What is the expected output? What do you see instead?
Content not supported

What browser are you using?  What version? On what operating system?
Canary build (41.0.2253.2 + )

Please provide any additional information below.
I did a build from the chromium repo (open source windows) and just uncommented 
the following lines in gpu_video_decoder.cc:

#if defined(OS_WIN)
  os_large_video_support = false;
#endif

Then ran the chromium build with the following command option:
--ignore-resolution-limits-for-accelerated-video-decode

This enabled content greater than 1080p.  The BDW GPU assisted decode show 
significantly less frames dropped when compared to software decode.  We will 
need to look at this functionality if enabled with the other platforms but 
results look promising.

And I can assert Rietveld renders just well in 1920p.
