/**

						|
 * Allow modules to alter a URL Pathologic is about to create.
 | 
						|
 *
 | 
						|
 * This hook is invoked after Pathologic has torn apart a URL it thinks it can
 | 
						|
 * alter properly and is just about to call the url() function to construct the
 | 
						|
 * new URL. Modules can alter the values that Pathologic is about to send to
 | 
						|
 * url(), or even stop Pathologic from altering a URL entirely.
 | 
						|
 *
 | 
						|
 * @param $url_params
 | 
						|
 *   An array with 'path' and 'options' values, which correspond to the $path
 | 
						|
 *   and $options parameters of the url() function. The 'options' array has an
 | 
						|
 *   extra parameter labeled 'use_original' which is set to FALSE by default.
 | 
						|
 *   This parameter is ignored by url(), but if its value is set to TRUE after
 | 
						|
 *   all alter hook invocations, Pathologic will return the original, unaltered
 | 
						|
 *   path it found in the content instead of calling url() and generating a new
 | 
						|
 *   one. Thus, it provides a way for modules to halt the alteration of paths
 | 
						|
 *   which Pathologic has incorrectly decided should be altered.
 | 
						|
 * @param $parts
 | 
						|
 *   This array contains the result of running parse_url() on the path that
 | 
						|
 *   Pathologic found in content, though Pathologic likely altered some of the
 | 
						|
 *   values in this array since. It contains another parameter, 'original',
 | 
						|
 *   which contains the original URL Pathologic found in the content, unaltered.
 | 
						|
 *   You should not alter this value in any way; to alter how Pathologic
 | 
						|
 *   constructs the new URL, alter $url_params instead.
 | 
						|
 * @param $settings
 | 
						|
 *   This contains the settings Pathologic is using to decide how to alter the
 | 
						|
 *   URL; some settings are from the graphical filter form and alterable by the
 | 
						|
 *   user, while others are determined programmatically. If you're looking for
 | 
						|
 *   the filter settings which Pathologic is currently using (if you've altered
 | 
						|
 *   your own field onto the filter settings form, for example), try looking in
 | 
						|
 *   $settings['current_settings'].
