Davis King 46401b0641 Changed the image_window so that it doesn't resize itself if you keep 
giving it images that are the same size.  This way if you are sending
video data to it will allow the user to change the size of the window
without having it snap right back.

Davis King 17e5172d53 Changed the display size of the boxes in this example so that each 
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.

Davis King 867756ca17 In addition to minor code cleanup I also changed the following: 
- 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.

Davis King d511810723 Added a check to the deserialization code for vector_normalizer objects that 
will detect if the user is trying to deserialize a vector_normalizer_pca object
into a vector_normalizer.  If so it throws serialization_error.

Davis King 4370a5f7ef Split the vector_normalizer into a normal normalizer and a pca normalizer 
version.  I did this mostly so that the normal version can return
matrix_type objects and thus avoid any reallocation of matrix objects
in client code.
