[fprint] Writing driver for Egistec reader (1c7a:0801)

[Алексей Прокопчук]

Finally, I realized how to assemble an complete image. Everything was much
easier than I thought at first. All that is needed - this is simply to
collect all eight received buffer in one common. The result is a correct
fingerprint image 192x640. There is no need any Mathematics - I've checked
dozens of times by different fingers - everything works properly.
Very interesting Scanner - a normal fingerprint image is obtained only if
the sweep finger on the scanner fast enough. If slow, a fingerprint
obtained is bad. I did not think that all will be so easy. :)

But now, the question remains: In which format should I submit the image
for processing in libfprint?

Now begins the most difficult and interesting part: everything I've done
in a standalone application, should be moved into the driver... It would
not be so simple as to deal with images, but I'll try.

Thank you very much for your help! I hope that soon a list of supported
hardware expands to one more device.
