[sane-devel] Gray frame with sane_control_option

Sounds good -- what are your goals? What can it do that xsane
etc. can't? Why not use GTK 2.x?

Some scanners don't support greyscale scanning. Therefore you'll
always get RGB images from the Coolscan2 backend, for example.

It would be nice to have a conversion algorithm incorporated into the
frontend. It would only have to be activated when the scanner is
incapable of supplying greyscale data.
