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.
Anything that isn't specified to the virtual pixel is an error in the
spec. (The canvas section is especially prone to these given my lack of a
graphics background.) In theory, the canvas section is supposed to specify
everything down to the level just before anti-aliasing.
I just want to point out here that optional support for shadows
contradicts this.
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,
David Flanagan
