It's not really new, it was checked into the git repository in April: http://cgit.freedesktop.org/xorg/app...4ba83ff9e6c207
. But there hasn't yet been a release that would include it. Once a release is made, distros will pick it up.
It's quite cool, for example on my netbook I can do this:
xrandr --output VGA1 --mode 1024x768 \
--output LVDS1 --mode 800x600 --scale-from 1024x768 --panning 1024x768 --same-as VGA1
Without the patch you can achieve the same effect, but you need to calculate scale factors manually. In my example, instead of "--scale-from 1024x768", you'd use "--scale 1.28x1.28"
