Public bug reported:

Hey!

This is a feature request for a Peirce quincuncial projection:
http://en.wikipedia.org/wiki/Peirce_quincuncial_projection

Equirectangular seems to be the most common type of projection for
storing panoramas, yes it is horrible for this purpose. Distortion
increases as you move further from the equator, and so the size and
distribution of pixels from the original source image (whether fisheye
or rectilinear) when forward-mapped into an equirectangular projection
varies wildly - this makes it a horrible projection considering how JPEG
compression works, considering one may want to denoise the panorama or
sharpen it, etc.

The Peirce quincuncial projection has very limited distortion. From
Wikipedia, "The part where the exaggeration of scale amounts to double
that at the centre is only 9% of the area of the sphere, against 13% for
the Mercator projection and 50% for the stereographic projection". When
used in cartography, it gives an honest representation of the globe.
When used for aesthetic purposes in panoramas, it gives a unique and
interesting look.

Please consider adding the Peirce quincuncial projection to Hugin.
