tight bounds optimization

Add support for tight bounds to detect and return moveTo
followed by close or zero-length lineTo.

Also short circuit so that hard work is avoided when
the path bounds is also the tight bounds.

Avoid doing work if the bounds can be trivially computed.
Include naked moveTo coordinates in the tight bounds.
