Umax port of SANE UMax 0.28 backend.
It supports properties:
- scanmode
- DPI
- contrast
- negative
- preview
- analoggammma
- threshold
- brightness
- scan source
depending of scanner's abilities.

This backend supports configuration file umax.conf in S: assign (only options
part).
If Your scanner doesn't work well in color mode try setting "option scan-lines"
to lower value (10).
It has been rewritten not to use fork() and pipe() so it doesn't require proper
queue-handler from MorphOS 2.3 and it's more stable than 68k version.
