It looks like mincnt is used only when C is not None. For the default
histogram method, I've found it useful to be able to turn off cells
with fewer then *mincnt* points. Attached is a diff which implements
this. Also, should *marginals* be True by default? It seems that
hexbin is an alternative to scatter and since scatter doesn't have it,
then hexbin should not have it either.
