EPS output from PS backend
Just add an eps extension
PS and EPS save from GTK and WX backends with bugs fixed
A few of the bugs that were lingering in the PS output from the GTK
backend have been cleared up. A fairly substantial refactoring of
the Text class enabled this. Text is now backend independent and
behaves like the other artists in the figure (lines, patches,
etc). Additionally, PS and EPS save from WX backend work
Object picker example
The file examples/object_picker.py is a template showing how to
select objects in the figure with the mouse(eg, text, lines). If you
click on the line, a properties dialog will pop up. You can edit the
line properties. This is just a template for those who want to
develop a GUI properties dialog. If interested, contact the mailing
list. It would be straight forward to extend this example to allow
you to move objects in the figure, etc
