Comment:
Path objects would be much more useful if their individual commands (moveTo,
lineTo, etc.) could be inspected from JavaScript. This would allow for the
JavaScript implementation of missing features such as text-to-path conversion,
boolean shape operations, custom transforms (e.g. perspective), custom stroke
styles, and so on.

Yeah, that's an obvious next step. One day.
Comment 2 Ian 'Hixie' Hickson 2013-10-14 21:34:13 UTC 
One problem with this is that it requires that we define exactly what the representation is, when it would otherwise need to be an approximation. Consider the path constructed out of text, or the path constructed out of stroking another path that contains a bezier curve.
