Lacking general input redirection, this is actually an often requested
feature, but unsupported by all compositors I'm aware of.

nb. that Qt (and maybe gtk) also operate on overriding settings
(environment variables) to scale the particular client beyond the
physical resolution (not sure whether that's relevant for Alberto's
scenario)
