This object takes care of mapping absolute devices to monitors, to do so it uses 3 heuristics, in this order of preference: - If a device is known to be builtin, it's assigned to the builtin monitor. - If input device and monitor match sizes (with an error margin of 5%) - If input device name and monitor vendor/product in EDID match somehow (from "full", through "partial", to just "vendor") The most favorable outputs are then assigned to each device, making sure not to assign two devices of the same kind to the same output. This object replaces (and is mostly 1:1 with) GsdDeviceMapper in g-s-d. That object would perform these same heuristics, and let mutter indirectly know through settings changes. This object allows doing the same in-process.
