Title:
  getFocalLength() warnings

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  [setting priority to 1 as this is just an annoyance and not a release blocker]

When remapping an equirectangular image with nona, I see four of these warnings, which makes it difficult to see the rest of the output:

  Lens.cpp:88) getFocalLength(): Focal length calculations only supported with rectilinear and fisheye images

In fact the hugin Assistant seems to be capable of calculating the focal length of an equirectangular image:  If I enter a FoV of 360 and multiplier of 1, it gives a focal length of 6.16mm - This is the same as for fisheye images and seems quite reasonable - ie. This is the focal length of lens that would be required on a rotating panoramic camera to give this image.
