In addition, I notice that Bio.Graphics.BasicChromosome,
Bio.Graphics.Comparative and Bio.Graphics.Distribution expect lower case
formats (currently just pdf and eps) while Bio.Graphics.GenomeDiagram expects
upper case.  We should be consistent, which for backwards compatibility would
mean accepting either case.

I've updated the docstrings in CVS,

Bio/Graphics/BasicChromosome.py revision 1.3
Bio/Graphics/Comparative.py revision 1.2
Bio/Graphics/Distribution.py revision 1.3
Bio/Graphics/GenomeDiagram/Diagram.py revision 1.3
