Color correcting projectors?

[Richard Hughes <hughsient gmail com>]

In GCM we currently support two types of display profiling. Internal
(LVDS) panels are internal to the system, and external panels (DVI and
the others) are external to the system.

What different settings do we need to do for projectors? We certainly
need to give different instructions (which we also need to write), but
will argyll just process these like a low-gamut LCD screen? Are there
any options we need to add?

Richard.
