Hi Team,

While going through Blink's commit, I came across potential assertion fix and also to improve handling NaN cases:

Blink Commit - https://src.chromium.org/viewvc/blink?revision=183090&view=revision

WebKit Source - https://github.com/WebKit/WebKit/blob/28de25b653f64ca3fc8e87fbf1d1a963329a5342/Source/WebCore/html/canvas/CanvasRenderingContext2DBase.cpp#L520

Unfortunately it does not have any test case to identify whether it is causing assert or failing or something but I just wanted to get input.

Thanks!
