Comment(by crschmidt):

 In safari, after applying this patch, I get something that looks better,
 but still 'not quite right'; it looks fine when I'm sketching, but as soon
 as the geometry is finalized, it has a 'half-fill' look to it.

 I guess the fact that it looks  okay while sketching isn't new; it looks
 like that's the case even without this change, so I guess that's not
 relevant. (But maybe helps to better understand a potential fix? Ohhhh,
 wait. The sketch handler is using the default SVG stuff on a separate
 layer, so that's why it works. Okay, so ignore that :)

 Okay, so knowing that, I think this is just because we're not setting the
 fillOpacity to 1.0 when drawing the inner ring. Attaching a patch that
 does that, which seems to fix the behavior I'm seeing.
