Also optimized the derivative() function a bit.

Most of these changes are just rearrangements of the old code.  However, I also changed
the starting value of a line search and also removed some unneeded calls to the objective
function and its derivative in the course of doing the refactoring.  This has all resulted
in a significant reduction in calls to the objective function.

video data to it will allow the user to change the size of the window
without having it snap right back.

box is the same size as the SURF window.  I thought the smaller boxes
were easier on the eyes but not using the SURF window size is probably
confusing.

   - The zoomable_region widget now uses exponential rather than linear
     zoom scaling since this is much more pleasing to use.  There is now
     a new requirement on the zoom increment that it must be between 0
     and 1.
   - I added a few missing requires clauses.
   - I changed the set_zoom_scale() function so that it actually changes
     the zoom scale even if the user requests a zoom value outside the
     allowed range.  It just uses the max or min allowed value rather than
     doing nothing.
