[Proj] rHEALPix new parameters

[support.mn at elisanet.fi]

Michael,

Proj.4 does not have any deep checking for parameters, it is
very basic and simple library. It just usually makes something
wrong without giving any error messages about the wrong
results. There was a discussion about to add a syntax checker
in front of proj.4, kind of a pre processor which would sort out
the most obvious errors. But that addition is waiting for a better
day to be done. Until then the user must be very careful not to
enter anything wrong to it.

Janne.
