+ * 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'].

+ * - - Our path parsing code needs to account for both new and old dirty URL
+ *     styles
+ * - - Option to force output of clean or dirty URLs?
+ * - Move _pathologic_filter() code into the actual filter class
+ * - Do DOM object manipulation instead of preg_replace(). It's what core

+ * - UrlHelper::Parse() instead of parse_url()?
