Backends use a mixture of SANE_CURRENT_{MAJOR | MINOR} and V_{MAJOR |
MINOR} with all kind of permutations. I was confused by this and one
comment in pieusb.c tells me I was not alone. Some items in old
changelogs suggest to use the SANE_CURRENT_ macros in backends, so let's
switch to do that with the exception of net.c and dll.c. Done with:
$ find backend -name '*.[ch]' | xargs sed -i '/nearly every/ ! { s/\<V_M/SANE_CURRENT_M/g }'
$ git checkout backend/net.c backend/dll.c
And manually removing the comment from pieusb.c. Everything still builds
fine.
With the exception of use in three quotes as well as our inlcuded copy
of the GPL, all use of the Free Software Foundation's postal address
has been removed.
Re #320.
Not all pthreads implementations use an integer type for pthread_t.
As a matter of fact, POSIX has explicitly withdrawn the requirement
that it must be an arithmatic type.
The musl C library uses a `struct __pthread *` which triggered the
warnings. As of this change, sanei_thread.h works around this by
providing two new macros to help keep this issue out of sight. All
backends have been changed to use these macros.
Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
Improve speed and reduce noise of most resolutions
Deal with an escape code discovered in the scanner's protocol
Use hardware detailed calibrations for resolutions up to 300
Use improved software detailed calibration for other resolutions
Add more debug information
Drop the 25dpi resolution
Make 200dpi the default (the same as the Windows frontend)
Add code (not used yet) to deal partially with grayscale and
lineart scanning
Use I18N strings where appropriate
