backend/pixma_sane_options.c backend/pixma_sane_options.h:
- added new options:
original (type of original to be scanned)
target (action to be perfomed as target of the scan)
Both these indocators can be returned by the scanner.
pixma_mp810 can definately return these (e.g. for my MP980)
I have assumed that the same applies to devices in pixma_mp150.c
The target used to be returned in button1/2 in bits 0 - 8.
- All button options are now read and cached when any of the options
are read (SANE_ACTION_GET_VALUE) or SANE_ACTION_SET_VALUE is used
on option button_update.
When reading an option again, the status of all options is re-read.
- Added a dummy info field that is used in case info is NULL
as this is a valid input
