RT-20302: Consider changing picking behavior of dashed strokes

[Jim Graham]

I think the justification that was given when we talked about this in 
the pre-FX days was that the dashes could be animated for a marquee 
effect and you wouldn't want to make it harder to click on them.  It's 
probably a lame example and I think others have given better arguments 
to why this behavior is not necessarily a bad thing, but I wanted to 
throw it out in case it rings a bell with any applications that are out 
there or planned...
