Thomas Thurman cf48407972 An attempt to keep all information about window bindings in the same 
2008-09-06  Thomas Thurman  <tthurman@gnome.org>

        An attempt to keep all information about window bindings
        in the same place.  Screen bindings to come.

        * src/core/window-bindings.h: new file, list of all window bindings
        * src/include/prefs.h: drop all the existing window-binding macros

        * src/core/schema-bindings.c (): output all the schema blocks that
        would appear in metacity.schema for these window bindings.  This
        ought to become part of the build process, and hopefully will soon.
        When this works it will also close #469361.

        * src/core/keybindings.c: generate handle_* prototypes using
        x-macros;  populate window_handlers using x-macros;  rename several
        functions to have consistent names;  do_handle_move_to_workspace(),
        handle_move_to_workspace_flip(), and handle_move_to_workspace() all
        merged into handle_move_to_workspace.

        * src/core/prefs.c: generate window_bindings and window_string_bindings
        using x-macros;  (meta_prefs_set_compositing_manager) fix unrelated
        problem with use of GConf functions when GConf was disabled.

        * src/core/core.c (meta_core_get_menu_accelerator): binding names
        given as literals since this is the only place in the code they
        now appear

/* Looks up the MetaWindow representing the frame of the given X window.
* Used as a helper function by a bunch of the functions below.
*
* FIXME: The functions that use this function throw the result away
* after use. Many of these functions tend to be called in small groups,
* which results in get_window() getting called several times in succession
* with the same parameters. We should profile to see whether this wastes
* much time, and if it does we should look into a generalised
* meta_core_get_window_info() which takes a bunch of pointers to variables
* to put its results in, and only fills in the non-null ones.
