Proposed patch v4

Updated patch with additional test coverage.
The spec isn't too explicit on how NaN/etc should be handled.
NaN/Infinity/null becomes 0 on Firefox and 300/150 (default value) on Opera.
Opera OTOH doesn't allow 0 width/height.
Personally, while I think mapping NaN/Infinity/null to the default values makes some sense,
it doesn't justify adding custom JS bindings to deal with these cases.
