Suppose you have a *LARGE* jpg file, and wish to load it. The simplest way is just to use imageio:

Image myImage = File("big.jpg"));

But what I'm finding, is that this takes much longer than can be accounted for by file IO even on machines with good GPUs, so it's obvious the GPU is not being used.

What I would like is for jpeg decomression to happen on the graphics card. Any thoughts?
