Renderers
Output renderer is a class with collection of methods that handle rendering of visual aspects of Moodle pages, emails, html export, etc. In 1.9 general output related functions were located in weblib.php and modules stored rendering code in lib.php, locallib.php, view.php, etc.
Output renderer instances are obtained through moodle_page::get_renderer($component, $subtype = null, $target = null) method. Current core_renderer is available through the global $OUTPUT variable, please note this global should not be used in low level APIs and scripts like cron.
