X reports a DPI for screens, but with randr 1.2 and xinerama, one X
screen may be made up of several physical screens so DPI is basically
meaningless in that case. RandR 1.2 allows clients to just set
whatever it wants the DPI to be.

The upcoming GNOME will simply set it to 96.

RandR 1.2 also exposes the EDID information from the monitors and
toolkits could in principle make use of that information if they
wanted to.
