This looks interesting, and the functionality is certainly nice, but
it looks like a brute force hammer approach when a scapel might be
preferable,  For example, what if we introduce a new kwarg fillstyle
with options 'full|top|bottom|left|right' so *any* marker could be
half filled.  This would result in both less code and more
functionality.  If you are interested in tackling this, I'd be happy
to consider a patch.  Please see
