This isn't currently possible, but it is an easy thing to add, so I will
do it for the next version. The reason it works the way it does is that
I never anticipated people would want to use variable numbers of
vertices (I've needed to do that myself), and in situations where you
are sharing a single vertex between multiple polygons (very common in
most 3d engines), it is more efficient to take a separate pointer to
each vertex than to require them to be copied to contiguous locations in
a temporary buffer. But there is no problem with supporting both types
of parameter, so I will add your method as well...
