* libgimp/gimpexport.c: get rid of remaining (invisible) layers
after merging visible layers
* app/channel_ops.[ch]: applied a patch from Garry R. Osgood that
seems to fix bugs #2261 and #2382 (crashes when using offset).
A few more changes made the dialog actually work...
* app/ops_buttons.c: plugged a memleak I introduced yesterday

* libgimp/gimpexport.c: handle CAN_HANDLE_LAYERS_AS_ANIMATIONS
correctly
* app/scan_convert.c: trivial optimizations
* app/nav_window.c: applied the patch from Shuji Narazaki that makes
the navigation window work with tablets. Fixed some rounding errors
and stopped the flicker.
