Destroy and clear methods seem to do exactly the same thing
@see http://svn.php.net/viewvc/pecl/imagick/trunk/imagick_class.c?view=markup (l.3066 & l.3087)

The code is duplicated, they do the same thing a bit differently.

One might be suprised that there seems to be no difference between:

<?php
$imagick = new Imagick();
$imagick->clear();
$imagick->readImage('myfile.jpg');
?>

and

<?php
$imagick = new Imagick();
$imagick->destroy();
$imagick->readImage('myfile.jpg');
?>

Both functions reset all options and clear all used resources so you might want to use either one of them.
