[PATCH 2/3 xf86-video-intel] Update the rotation property whenever we change the rotation.

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Don't worry if that fails: only the KVMr feature will be affected.

We still need to change the sna/ code.

[PATCH 3/3 xf86-video-intel] Add underscan properties

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

In the Kernel side, these are crtc properties (since in the hardware,
underscan use the panel fitters, which are attached to the pipes).
Ideally we should make these as crtc properties too, but since xrandr
doesn't have support for them, we expose the atoms as output
properties. This is not the best solution, but making the kernel
underscan properties be output properties instead of crtc properties
would be even more wrong.

We still need to change the sna/ code.
