Parse EDID for missing modes (ultrawide issue)

For some reason X ignores ultrawide resolutions in the EDID data...
Additionally (at least on LG models) the EDID data wrongly says 1080p
would be the preferred resolution of the screen, so we now take the
physical dimensions of the screen into account and override that
decision, if applicable. This assumes square pixels, but that shouldn't
be too crazy of an assumption.
