(*numsides*, *style*, *angle*) see below
============================== ===============================================
The marker can also be a tuple (*numsides*, *style*, *angle*), which
will create a custom, regular symbol.
*numsides*:
the number of sides
*style*:
the style of the regular symbol:
===== =============================================
Value Description
===== =============================================
0 a regular polygon
1 a star-like symbol
2 an asterisk
3 a circle (*numsides* and *angle* is ignored)
===== =============================================
*angle*:
the angle of rotation of the symbol
For backward compatibility, the form (*verts*, 0) is also accepted,
but it is equivalent to just *verts* for giving a raw set of vertices
that define the shape.
