I'm currently investigating rotation in Marble [1]. Rotation in spherical projection works pretty nice already, whereas the flat projections still need work. Besides making the flat projections rotation-aware, I'm still investigating on how to eliminate singularity issues for the flat maps, which cause the map to be centered at lon=0° when the map is moved to 90° north or south.

Moreover, I'm also not sure how manual rotation should be triggered. In my branch, I changed the RMB context menu to appear when the right mouse button is released, such that rotation is possible as long as it is pressed. Any suggestions, also from the other Marbleheads, are very welcome!

Greetings,
Bernhard
