There is nothing out of the box for this at the moment. The usual trick is to 
draw a hi-res version of your scene in a tiled manner using a custom camera 
frustum into a texture attached to a framebuffer object. That can all be done 
with some manual tweaking of a framegraph. The bit I am unsure of at the 
moment is reading back the rendered pixel data to the CPU side.

Could you file a JIRA request for this please and we will see how best to fit it 
into our plans?

Thanks,

Sean
