I've placed a patch here:

Give that a try.  All you need to do is put your code for saving as PNG 
or whatnot in the location provided in the new switch statement.  You 
may also want to tweak things, e.g., change the filters to whatever 
files you can save as.

This is slightly different than the way Qt behaves as far as picking a 
file format.  It's done via the file dialog's filter feature.  It makes 
for a more conventional method of choosing, and in fact makes for easier 
programming versus putting a dropdown menu associated with the toolbar 
button.  I suggest adding your code and moving into the repository then 
let people compare/experiment.  If people prefer the dropdown menu, I 
can give that a try.

Note that for the file icon I simply used one of the standard stock 
icons for wxWidgets, the wxART_FILE_SAVE_AS icon (suggested size 
wxART_TOOLBAR).  So, the icon should be the same as you see in GTK, KDE 
or whatever.  I saw in the icons directory how to convert a PNG file, 
but before doing that I thought I'd give this a try.
