[Proj] List of supported projections and ellipsoids

[LOTT Jean-Baptiste]

Hi Frank,

Thanks for the answer, I saw they were in projects.h but I had some compilation errors while including it so that meant to me that it's not the right thing to do. I'll try to figure it out for the short term but I think it would be good to put them int proj_api.h. In my case I want to let the user know which projection he wants to apply to his map, so the goal is to offer a list of projections from where he can choose the one he wants.

Thanks,

Jean-Baptiste,

I see that those functions and the structure defines they are based on
are not currently part of the public api in proj_api.h.  However, they
are available if you include the internal projects.h include file.  I
generally discourage this, but it may still be the expedient thing for
you to do.

I might make sense to move these structure definitions and function
prototypes to proj_api.h if we want to consider them generally available.

Best regards,
