OK, to implement a default physical size for targets that are unable to know their physical size, or an override for targets that should know it but are misconfigured, it looks to me like I have two options: 1) Add a new environment variable e.g. GGI_HINTS 2) Add a -sizemm option to each and every target (except for ones like display-sub, which can always derive the info from its slave target.) #2 strikes me as cleaner.
