Lester, this is not a support list. It is your good right to stick with dead PHP versions and 10 years old code (whether it is your choice or not), but it is definitively not good to constantly posts totally off topic posts, replies or complains about what we do or don't. It is even more annoying in cases where you clearly do not understand the underlying reasons of one feature or another. That being said, I would love to see you actually contribute something for a change. Cheers, -- Pierre @pierrejoye | http://www.libgd.org
