o Banding suppression code.
o High-frequency noise suppression.
o Green channels local averaging to suppress maze artifacts.
o OpenMP speed-up in median filters (demosaic pack GPL2)
o OpenMP speed-up in green equilibration (demosaic pack GPL3)
* Bug fixes and improvements:
o Better parsing of unknown command-line params in dcraw_emu sample
o Brigtness table in ahd_demosaic is calculated in reversed order to prevent
possible (very unlikely) multithreaded app problem.
o Fixed file extension in half_mt.c sample.
o Fixed incomplete data fields reset in LibRaw::recycle()
o Patches for ./configure system for better LCMS2 support
o math.h included before any other includes to make KDE compile with Visual
C++ happy
o Fuji FinePix S5500 size adjusted to ignore (rare?) garbage at top of frame.
LibRaw 0.12.4 (2011-02-05)
* Fixed green matching/half-size incompatibility.
* New operations: max-rgb, pixelise, motion blur.
* Fixed a bugs in matting-levin that made GEGL halt due to errors
detected by babl sanity code, this made 0.1.4 be unusable if you had
all dependendency when building.
* build/test improvements.
* Buffer:
Added API to use external tile backends, allowing to plug-in alien
tilebackends, for GIMP/Krita/OSM or similar.
Fixes:
* Cannot extract exif data from Pentax K-x DNG file.
* Crash when writing Exif.Image.Software.
* Assertion in XmpParser::encode should be an exception.
* Regression: Compilation error with EXV_HAVE_XMP_TOOLKIT undefined.
* Regression: Panasonic RW2 files are missing information.
* Updated configuration files (config.guess, config.sub).
* Added new Color Label value to digiKam 2.0.0 XMP namespace.
