I've been browsing various scripts, and this comes up often. I understand it has something to do with graphics memory, but I haven't found anything specific about it or why it's being used. Any help much appreciated.
Hi,
It is documented in the Wiki now, but I just added some details about how it works:

Thank you, that makes sense now.
