Public bug reported:

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

** Affects: hugin
