EPSG:3857 doesn't render the map correctly.

[edigiacomo]

With EPSG:4326 the map is not rendered correctly. I think that the bounding box should be converted to lat/lon before passing it to macro.mmap. I'll file a PR soon to show a possible fix using pyproj.

I am not familiar with leaflet, then I had difficulty to try the projection .. Magics can understand projection coordinates .. I think I have just forgotten to set it in case of 3857 .. I will check that, not need for pyproj yet ! ( just trying to keep the dependancies minimum)

Can you show me how you set the projection in leaflet ? I am not sure I got it right !

In this patch you can see how to explicitly set the projection in leaflet:

Great, Thanks..

I will try now ..
Hoping to fix it without to have to use pyproj .

I think I will also try to improve the leaflet demo then we can do more manual tests with projection, and version .

Thank you, I tested it works fine now!
