note 95749 deleted from function.imagerotate by cmb

Note Submitter: edwins at xs4all dot net ---- This function apparently contains a memory leak. Because of this, it was kept out of the GD library that comes with Ubuntu (and I assume other OS'es, too). So, If you are running Ubuntu and wonder why you get "Call to undefined function imagerotate()" even though you seemingly have the correct GD lib installed, this is why. Use the alternative supplied by beau at dragonflydevelopment dot com instead. It works flawlessly (for angles in steps of 90 degrees). On a side-note, some other GD image functions (unfortunately, the more interesting ones) suffer from the same problem and are kept out of the Ubuntu distribution as well.
