Status of OpenSlide support

Hi Adam and Martin,
   Is #5 (inability to do commit changes without the help of one of the original
developers) really the showstopper at present?   I don't have that impression, but
if that's the case it is easily fixed by us granting permission to specific,
carefully-vetted individuals.   We don't have a community-developed
process in place, but for a small number of individuals it shouldn't be a 
big deal.  If you can convince Adam Goode, Benjamin Gilbert, and Jan Harkes
that you can be trusted with this role (and they tell me so), 
I can work out the mechanism.   There is no need to create a fork just to
be able to commit changes to the OpenSlide code base. 

My understanding is that it is #1 and #2 (lack of time and expertise) that is
the limiting factor to OpenSlide evolution at the moment.  Adam's advice
on #1 to #4 are right on target for  addressing that.
