Depending on your PHP and GD versions this function is defined or not. With
PHP 4.0.6 through 4.1.x this function always exists if the GD module is
loaded, but calling it without GD2 being installed PHP will issue a fatal
error and exit. With PHP 4.2.x this behaviour is different in issuing a
warning instead of an error. Other versions only define this function, if
the correct GD version is installed.
