XRandR: fix screen size calculation 

XWindowsScreen::saveShape() using XRRSizes / XRRRotations to
calculate screen dimensions when XRandR and a rotated screen
was detected. This is wrong. The screen dimensions in the
display properties already reflect rotation.

Moreover, on servers supporting XRandR >= 1.2, the XRRSizes()
and XRRRotations calls from XRandR 1.1 will return the
properties of the "primary output" in XRandR 1.2 terms rather than
the properties of the entire screen.
