Thanks again.  I committed most patches to repository (some were
slightly modified).

For ImageVariableGroup.patch: I made Panorama::getImage inline. GetImage
should only return the address of the SrcPanoImage class, nothing more
is happen in this function. I don't know why this should be so expensive
(or is the lookup in the std::vector so expensive?)

Title:
  PATCH: speed improvements

Status in Hugin:
  Fix Committed

Bug description:
  I tried to profile hugin on a large project with 500 images and 100000
  control points. I identified and fixed some bottlenecks:

  ImageVariable.patch - reimplemented ImageVariable with shared_ptr -
  reduces complexity from O(n) to O(1)

  ImageVariableGroup.patch - move some method calls out of a loop

  GreatCircles.patch - reduce number of segments for short lines

  GreatCircles-image.patch - HuginBase::SrcPanoImage is expensive,
  initialize equirectangularImage only once
