Tracking back from the monitor to the output every time we need to
figure out the scale of a window on a monitor is inconvenient, so
propagate the scale from the output to the monitor it is associated
with.

So that clients such as the control center can decide to hide an
underscanning checkbutton when the output does not support it.
Support in the KMS / native backend to come later...
The monitors info structure is created from the tiled outputs
and this is used as the central storage for info about a monitor
as opposed to the output state.
It appears at least the EDID mm w/h is for the whole monitor and
not per tile.
this just adds backend support for retrieving the tile
information from X11 (randr 1.5) and native backends.
It stores the tiling information into the output struct.
Some DRM drivers have added a consistent set of properties that
allow compensating for the overscan that some TVs do, without the
user being able to disable.
This function returns the monitor_info index corresponding to the given
coordinates, or -1 if none is found at that point. The native backend
has been changed in places where it could make use of this function.

This just exposes the type and the singleton getter necessary to make
it available to introspection. We'll expose more functionality as it
becomes needed.
