Greetings to everyone,

I am using MarbleWidget for a project, and I need to display the map in the Azimuthal Equidistant projection, but I need to fix the projection focus in advance. Currently, when I perform panning, the focus change and it is moved always to the viewport's center, remapping everything. What I need is to translate everything without remapping. Is it possible to do what I need?

On the same subject, I would like also to increment the clipping radius. The Azimuthal Equidistant projection, mathematically, can be clipped right before the earth's opposite point. Is it possible to change this parameter as well?

If these features are not implemented yet, can I have some orientation on which parts of the source code to modify in order to do this?

Thanks in advance to everyone
