Re: Expected behavior for stroke-dasharray="0"

Hi Thomas,

As you mentioned, the SVG 1.1 specs say:

http://www.w3.org/TR/SVG/painting.html#StrokeDasharrayProperty

Which makes the behavior you mention definitely a bug.  Out of curiosity,
which browser is not currently displaying the stroke in this case?

The SVG 2 draft includes much more detailed implementation instructions for
stroking to deal with additional edge cases; these reinforce the above
expectation, if you follow through the algorithms carefully.
