* app/context_manager.c: namespace cleanups.
* app/commands.[ch]
* app/menus.c: moved the "Toggle Selection" menu entry to "View",
sprinkled some separators and made the layers/channels/paths popup
menus consistent with Tigert's last ops buttons change.
* app/fileops.c
* app/plug_in.c: check for gdisplay_active() returning NULL in
some more places.
* app/[all tool related files]:
- Turned the ToolAction and ToolState #define's into typedef'ed
enums, so the compiler can do some more sanity checking.
- Removed one more unused global variable "active_tool_layer".
- Removed some #include's from tools.c.
- Standardized the individual tools' structure names.
- Moved showing/hiding the tool options to separate functions.
- Stuff...
* app/commands.c
* app/disp_callbacks.c
* app/gdisplay.c
* app/tools.c: fixed the segfaults which happened when the image
of one of the tools which have dialogs (levels/posterize/...) was
deleted. My approach was to do stricter sanity checking and to set
some gdisplay pointers correctly where appropriate, so I can't
tell exactly where the bug was.
The curves tool now(??) updates on every _second_ display change
only, which is really obscure.
Finding/changing the display to operate on should definitely be
done by connecting to the user context's "display_changed"
signal.
* app/gimpset.c: emit the "remove" signal _after_ removing the
pointer from the set. If this was not a bug but a feature, please
let me know, we'll need two signals then.
