[Bioc-devel] imageMap in package genplotter has wrong signature

[Wolfgang Huber]

Hi Florian: please go ahead an check in your fix.
All: should we set the maintainer for geneplotter, genefilter, Biobase 
to be "bioc-devel"? This might lower the threshold for some to contribute?

  Cheers
  Wolfgang
