We would like to force all the interface elements to be on the center monitor in a three monitor setup.
If the game is running at 5760x1080 (3 1920x1080 monitors), the interface spreads out (as it should, as NGUI is just handling things properly from a resolution independent POV).
Is there a way to "trick" NGUI into thinking the interface should be displayed using 1920x1080 with the top-left pixel being (1921,0), when the "real" resolution is 5760x1080?
That would ensure all the interface stays centered on the center monitor, which is what we want in our case.
