Extract a stereographic 'little planet' from an equirectangular image
Generates a suitably sized stereographic .pto project from a 360 degree equirectangular image. Input is in any image format understood by hugin, output is in square TIFF format with a field of view of 253.7398 degrees (this places the horizon halfway between the centre and the edge).
The output filename is derived automatically from the input filename with '-sgraphic.pto' appended. Existing .pto files will not be clobbered but will be updated when input images change size.
