This is just a guess: one difference between scanimage and
xscanimage is that xscanimage uses the backend's get_select_fd()
function. You could try to force snapscan's get_select_fd() to
always return SANE_STATUS_UNSUPPORTED, and see if it works then.
(snapscan's get_select_fd returns the file descriptor fd of a pipe
which is also used to transfer the image data. If a frontend
tried to test readability using something like
try to get character from fd, the put it back
data would be lost, the image presumably sheared.)
