* DisplayDevice.cs: Made DisplayDevice properties settable

internally (simplifies device detection code).
Bounds property is now independent of the default resolution.

* DisplayResolution.cs: Obsoleted the Bounds property, as this becomes
  invalid as soon as the resolution of any display device is changed.
