OK, to be more precise:

The RandR extension only changes {pScreen,pScrn}->virtual? (and the
pScreen->mm{width,height} fields), but not anything else. The root
window is created immediately after all ScreenInit()'s and takes the
original pScreen->virtual? for its size. And it stays in that size
throughout server lifetime.
