Most of this had been applied upstream (or was taken from upstream).
The only thing left was adding an include of string.h, but it builds
w/o warnings without it, so that appears no longer necessary.
pkgsrc notes:
* I know 0.2.7 is out; it has issues on ubuntu so I'm doing this first.
* patch-ac should perhaps be dropped.
Upstream NEWS content (from web page):
* more than 40 new database entries of lenses and compact cameras
* new CMake based build system for better cross platform compatibility
and compilation fixes for MSVC
* better integration into hugin for loading and storing lens
parameters via the lensfun library
* several bug fixes and stability improvements
This release not only publishes all database additions that were
contributed in the last half of year, but also introduces several
new improvements in the library itself.
* As always, many new lenses/camera were added to the database
* Support for cross-platform compilation using cross-mingw32
(build instructions in README).
* Some bugs were fixed in the library, related to memory
allocation. Now lensfun should be valgrind-clean.
* Fixed a nasty bug in lfDatabase::FindLenses() that would
always use fuzzy search (even if you would ask for a 100%
match). Your applications may chease to "find" lenses if they
relied on this bug. Just add the LF_SEARCH_LOOSE flag as the
last parameter to return the old behaviour.
* Fixed another bug in search logic that sometimes would mark
unappropiate results with very high scores (esp. when little
search keywords are given). Now search should work much better.
* New TCA correction algorithm: LF_TCA_MODEL_POLY3 ("poly3" in
database). This is almost the algorithm used by Hugin except
the highest-order power (r^4). This should allow users to use
tca_correct to compute TCA parameters.
* Fixed the LF_TCA_MODEL_LINEAR - it used 1/k where it was
expected to use k. This is the 'v' parameter of Hugin TCA model,
and previously users had to invert v to get k; now they can
just use v.
* New lens calibration tutorial, using Hugin.
* Some SSE & SSE2 support from Klaus Post with runtime CPU
features detection.
