This is actually a result of not exposing the CanvasRenderingContext2D
constructor on the Window object.  This can be seen by calling typing
javascript:alert(typeof CanvasRenderingContext2D) int the address bar and
seeing that it alerts undefined.  This is a bug and should be fixed.  We should
do an audit of what other constructors we are missing as well.
