Memory Warnings

Hi All,

I have been digging through the mailing list to find out different ways to deal with the -didReceiveMemoryWarning message. It looks like two different approaches has been implemented by different people (a callback and a system event).

As far as I can see, none of this has made its way into the main branch yet? I have a ton of high-res 2D animations which are causing a bunch of warnings on low-end iOS devices (especially iPad 1).

I am right now considering making the necessary change in SDL myself, but was curious if anyone had some recent developments?
