DevTools: screenshots broken by tainted canvas

Project Member Reported by paulir...@chromium.org, Mar 30 2016 
inspector.js:1496 SecurityError: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported. Error: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.
    at Error (native)
    at Object.screenshotCaptured (chrome-devtools://devtools/bundled/inspector.js:10806:143)

Repro:
1. Take a screenshot in responsive mode
2. change to nexus 5x, which adds device art
3. Take another screenshot

Odd, can't repro on Linux; tried undocking & different pages & changing zoom.

Oh, you're using remote debugging and that's causing cross origin errors? pfeldman@ can you take a look please?

no remote debugging. just emulation

i think the inner device art tainted the canvas.
