I went ahead and implemented this.  The user can now specify
'markercoloralt'.  In the process, I finished the "half-marker" code
for all remaining filled_markers.   The diff is attached, which also
includes a fix for bug #560720:

Please comment.  If there are no comments in a few days, I'll file a ticket.

A picture demonstrating this functionality is attached.  Demos for all
filled markers can be obtained here:

Note, the diff contains the script used to generate the pictures. More
generally, I wonder if there should be a 'markerangle' keyword. I can
probably push through and implement this, but I'd like to hear what
people think about it.
