Matthieu,

Thanks for your input!

I will change the project CRS by default but make it optional.

Do you have a xml file for the TMS of the Global Forest Change, or any info
on what server it uses or at least the path?

While working on it I realized the power of the caching - I am taking
advantage of that and setting the proper cache directory.

cheers
Etienne
