[sane-devel] VEHO film scanner test application started

I am still working on this. I have a test application which seems to
correctly scan my slides. I have been on vacation and catching up, but I
will be back working on this (and perhaps have a little more progress to
report) sometime in the next week or so.
My ultimate goal is to integrate it with the rest of the SANE family of
devices and then use xsane or something to scan my backlog of negatives.
Your help with testing will be greatly appreciated once I have something
which works (even a little).

I will keep you informed of my progress and when I need some testing help.

From my reverse engineering, this scanner does behave quite a bit like
a video camera. Once the setup commands are sent to the USB device, the
scanner repeats sending the image (sort of like the frames of a video).
