Ah, I see. Nice idea. Unfortunately, rotation is currently not supported
in Marble-master at all. I have an experimental "rotation" branch in my
github repository[1], where it's possible to rotate the map. However, only
spherical projection works correctly at the moment, whereas there is
almost no rotation support for the flat projections. I'd appreciate any
help, though! If you need more information, don't hesitate to ask.

Greetings,
Bernhard
