[BioC] Different colors in vennDiagram?

[Dan Du]

Hi Leif,

A little dig in the vennDiagrm source code shows that, when there are 4
or 5 sets, all function calls to draw set with 'polygon' use only the
first argument in circle.col, e.g.

polygon(relocate_elp(elps, 378, 145, 200), border = circle.col[1], lwd =
lwd)

Some simple fork will do, just replacing those circle.col[1] with the
right index.
