I looked up the iOS snapshot code. It looks to me as if it renders the contents of the window into a bitmap context. I've written my own screen snapshot and video recording code on iOS and this doesn't capture the contents of a view/window drawn directly with OpenGL - for that you need to read back the pixels from the hardware graphics accelerator directly.
So if my understanding of "accelerated rendering" is correct, then this shouldn't work - if LiveCode didn't block you making the call in that mode, you should get back a black image. I'm hoping to find out how to trace my way down from a command to the code that implements it in a workshop on Thursday. Curious to look at this one some more when I understand the code better.
