describes the exact transformation used.
- Fixed a bug in rotate_image(), it returned a point_transform_affine object
  that did the opposite of what the specification said it returns.

output pixel exactly the same way as defined by centered_rect().

visual studio 2010.  So I just replaced the uses of the typedef
with the actual type.

if no dynamic version of these libraries are installed on the system.

cmake can't find a copy to dynamically link to.  This is especially
useful on windows where cmake never finds libjpeg.

in visual studio based on the setting of the /arch compiler option.

won't inline them.

the 2011 paper Introduction to dual decomposition for inference by David
Sontag, Amir Globerson, and Tommi Jaakkola since the original 2008 paper had an
error in the algorithm that negatively effected its convergence.  Thanks to
James Gunning for pointing this out.

made during object detection.

changed the interfaces to these functions slightly.  Instead of taking a double that
determines how we decide if boxes match, they now take a test_box_overlap object.

Also added overlaps_any_box().
