This is the first checkin of a bunch of code refactoring I have been doing to this component. · 7831ae02

Davis King authored Sep 05, 2009

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.

In addition to minor code cleanup I also changed the following: · 867756ca

Davis King authored Aug 29, 2009

   - 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.
