Drawing jpg regions for Trick play thumbnails on roSGScreen

Hi

I’m trying to implement trick play thumbnails by drawing regions of a jpg image (downloaded from a server), as the user scrolls through a video in a custom Video node (basically what YouTube does). From what I understand from the docs, you can do this easily on an roScreen node, but my app is using an roSGScreen canvas (not sure if this makes a difference, but in my mind you can’t have both).

What would be the best way of doing this?
