visualizemap does not indicate overhangs

[jan-glx]

from queen import *
fragment = QUEEN(seq="CCGGTATGCG----/----ATACGCAGCT") 
fragment.printsequence(display=True)
fig = visualizemap(fragment, seq= True )
fig = visualizemap(fragment, seq=True, rcseq = True)

I'd expect overhang bases to be grayed/alphaed out instead.
