Alice 2.2 beta released!

Can't specifically say anything re Alice 2.2 Beta (other than it has never worked well for me) - but screen capture (which is the video output approach 2.2 Beta uses) and 3D graphics programs are both notorious memory hogs - for the code itself, for buffer space for the code and for the output data. That's a basic reason most of the work is handed off to hardware accelerators and graphics engines, rather than being done in software.
