I have checked in a few changes that I thought I should mention.
1) I have added a point of interest tool (similar to the existing
region of interest tool) that allows the user to select a point
without requiring a shapes layer. This shouldn't affect the
operation of the older tools at all, as it's just another radio button
option on the edit toolbar.
2) I have added a rudimentary mechanism for adding custom tools
to openev's menus. Currently the tools are introduced by
initializing GViewApp with a toolfile parameter. The toolfile
is a key=value text file that specifies module and tool
names. I have checked in an example toolfile (toolfile_example.txt)
and module (toolexample.py) to demonstrate how to create a new
tool and load it into gviewapp
(run "openev -t <path to toolfile_example.txt>" to try it).
I have tried to make the changes as transparent as possible, so
they shouldn't affect how openev operates without
toolfiles (unless you're opening an image file named -t),
but let me know if you run into problems that appear to be
