Cool stuff for drm connectors on same framebuffer #8

Hey there,

I ran into your code by chance, compiled it for my pi, it works great!

Reason why I'm here: I have 2 displays on a headless raspberry pi, I just couldn't get fbi to send its output to a specific drm connector, as both screens appear under the same framebuffer with the default raspberry pi driver. Your code did the trick.

I was thinking, wouldn't it be nice if drm-framebuffer could refresh the framebuffer as soon as a new image is passed to it? Right now it collects the framebuffer data, displays it, and then wait until it gets killed. I'll try to see if I can tweak your code and do a pull when I get a chance.

Thanks.
