special conditions:
hand scan interface --
with hand scanners the dialog box has a scan
frame which gets filled with image data. the
dialog box must remain up during reads, so we
use the exported frame_open, cacheptr, and
frame_close to create the frame instead of
device reads. Devopen just returns devcaps,
devstart does everything else.
special willow gs --
the gs board has 4 different buffers, which
contain the following: 0-even pix/even lines,
1-odd pix/even lines, 2-even pix/odd lines,
3-odd pix/odd lines.
each call to devread will layer the data so
that the buffers will be combined correctly.
