I believe that most of these issues can and should be left to the
implementation. If the implementation is allowed to choose whether or
not to draw shadows, then I think it is fine to allow the implementation
to choose the minor details of dash rendering.

I just want to point out here that optional support for shadows
And I think I'm ready to drop this now. I've posted an entry on my
(low-readership) blog about the (surprising, I think) fact that there is
no plan to add support for dashed lines. Maybe that will generate a few
more requests for the feature. Or maybe you're right and no one except
me really cares about this :-)
Thanks for all your time on this matter,
