/* options.c - code for handling user choices */
/* How it works:
*
* On startup:
*
* - The <Choices>/PROJECT/Options file is read in, which contains a list of
* name/value pairs, and these are stored in the 'loading' hash table.
*
* - Each part of the filer then calls option_add_int(), or a related function,
* supplying the name for each option and a default value. Once an option is
* registered, it is removed from the loading table.
*
* - If things need to happen when values change, modules register with
* option_add_notify().
*
* - option_register_widget() can be used during initialisation (any time
* before the Options box is displayed) to tell the system how to render a
* particular type of option.
*
* - Finally, all notify callbacks are called. Use the Option->has_changed
* field to work out what has changed from the defaults.
*
* When the user opens the Options box:
*
* - The Options.xml file is read and used to create the Options dialog box.
* Each element in the file has a key corresponding to an option named
* above.
*
* - For each widget in the box, the current value of the option is used to
* set the widget's state.
*
* - All current values are saved for a possible Revert later.
*
* When the user changes an option or clicks on Revert:
*
* - The option values are updated.
*
* - All notify callbacks are called. Use the Option->has_changed field
* to see what changed.
*
* When OK is clicked:
*
* - If anything changed then:
* - All the options are written to the filesystem
* - The saver_callbacks are called.
