Description Justin Palmer 2012-04-24 11:22:54 PDT 
We started receiving reports that some of the impact graphs on http://github.com weren't rendering.  After reaching out to someone on the chrome team, it seems this is because webkit doesn't support canvas elements that are wider than 32k pixels and fails without an error.   This was tested under Chrome Version 20.0.1105.0 dev.  Safari Version 5.1.5 (7534.55.3) and Firefox 12.0 will render the impact charts correctly.

James Robinson says this is a hard limit in Skia that is enforced here: http://trac.webkit.org/browser/trunk/Source/WebCore/html/HTMLCanvasElement.cpp?rev=114437#L78
