PHPXRef 0.7 : Drupal 6 (gatewave) : Detail view of imagecache.module

Return a URL that points to the location of a derivative of the
original image transformed with the given preset.

Special care is taken to make this work with the possible combinations of
Clean URLs and public/private downloads. For example, when Clean URLs are not
available an URL with query should be returned, like
http://example.com/?q=files/imagecache/foo.jpg, so that imagecache is able
intercept the request for this file.

This code is very similar to the Drupal core function file_create_url(), but
handles the case of Clean URLs and public downloads differently however.
