Add option for Live Screen to use absolute mouse events instead of relative ones

I run Windows 8, which has a really good touch UI. When using the Live Screen option it would therefore be really nice if it could send the touch events I create on my Android (or other) device directly to the server, using absolute coordinates instead of relative movements.

To have this work on all devices and resolutions you will probably need to do a little math to send the coordinates over as percentages so that everything scales nicely, but I do think this is quite doable, and it would make a great addition!
