 // The format for requesting an icon is as follows:
 //   chrome://extension-icon/<extension_id>/<icon_size>/<match_type>?[options]
 //
 //   Parameters (<> required, [] optional):
 //    <extension_id>  = the id of the extension
 //    <icon_size>     = the size of the icon, as the integer value of the
 //                      corresponding Extension:Icons enum.
