As jamesr pointed out on IRC, there may be instances where supportsContext returns true but getContext fails. I think that's ok.

The suggestion is that supportsContext is the implementation saying if it does support a context in theory. A return value of false is a clear indication that getContext will fail.

This would allow an implementation that supports WebGL but not on particular hardware to return false.
