[sane-devel] Avision patch #2 - transparency light-box

[Dave Platt]

This patch fixes a problem with Avision scanners when the
"-source Transparency" option to scanimage is used to make
scans of photographic negatives or slides.

Without this option, the "-source Transparency" option can
be used once, but subsequent scans will probably hang and error
out (the "wait for the light to warm up" loop doesn't understand
the "backlight is on" status code).

I'd appreciate testing of this patch, to make sure that the
added wait_4_light() call doesn't cause problems on some
scanners.
