matrix with NaN values or by dropping the method call.

Change Description: no spec change
Rationale: from https://www.w3.org/Bugs/Public/show_bug.cgi?id=17468:
The spec says "Except where otherwise specified, for the 2D context interface, any method call with a numeric argument whose value is infinite or a NaN value must be ignored."
