I removed the stroke_opacity entity completely.  Bert also pointed out that
I was accidentally setting stroke_opacity on stroke elements that had the
fill color.  This fixes that glitch as well.  Of course, that fixed, I do
recognize that in the cases where a stroke is rendered in fill color, there
may be some potential oddities in the rendering.  As it's now been proven
that people do have use for this, perhaps we we'll opt to keep the "hack"
and forget the opacity completely.

I guess I'm going to ponder this and bring it up with the other developers
for the next day or so before finalizing it on the wiki.  Sorry for the
delay, but thanks for all the discussion!  It's been really helpful.  Please
let me know if you find any more bugs or have ideas for new features the
script could handle to make things easier.
