Changelog:
2018-04-10 babl-0.1.46
added extensions with more coverage for u32, half and other utilit fast paths
improving fast path coverage.
2018-02-18 babl-0.1.44
Fix bug in custom primaries/ICC fast paths, improve meson build<br/>
2018-01-23 babl-0.1.42
Fully initialize fishes when loading from cache. <br/>
2018-01-16 babl-0.1.40
Added format "CIE XYZ alpha" color model and formats.
New API babl_process_rows for reduced overhead in some scenarios; though bigger
gains seen also for regular babl_process with reimplemented branch-free
dispatch, and faster cbrt. Added meson build; being tested in parallel with
auotmake, Improved reference conversions for formats skipping some of models
components, Fixed gamma handling in indexed/palettized formats and improved
gamma precision consistenct in sse2 conversions.<br/>
2017-11-15 babl-0.1.38
Added format "CIE L float", a couple of protections against division by 0.0
2017-11-10 babl-0.1.36
Optimized customized primary aware code paths for CIE Lab<->RGB conversions,
improved accuracy of gamma approximations. New API babl_format_exists() for
checking validity of babl format name, crash proofing of cache handling and use
of environment variables.
2017-10-06 babl-0.1.34
Brown paper bag release, Fix indexed / custom primaries conflict, and re-export
a symbol used by old GEGL/GIMPs.
2017-10-03 babl-0.1.32
Added custom primaries and TRC support through ICC parsing, improved
float<->half performance, rewrite of all conversions functions to adhere to new
signature.
2017-07-15 babl-0.1.30
Thread stability for palette modes, stricter alpha preservation, now
cross-compilable on android.
2017-05-30 babl-0.1.28
Fast paths for Lav <-> Lch, release triggered by pending GIMP release.
2017-05-09 babl-0.1.26
Build and install HCY color space, platform independences fixes to fish cache.
2017-02-01 babl-0.1.24
Improvements to profile cache persistance, fast paths that improve actual GIMP
use on various precisions, use single precision constants for some more of CIE
computions.
2016-11-05 babl-0.1.22
Added cache of profiled conversions, added HCY color model, some precision and
performance updated for fast paths.
2016-11-05 babl-0.1.20
Fix run-time errors, leaks, and race conditions. Add conditional fast paths.
2016-06-13 babl-0.1.18
Bugfix: take alpha threshold in consideration when processing floats in SSE2.
2016-02-12 babl-0.1.16
Improvements to half float reference, SIMD, and fast-paths, and CIE float fast
paths; cleanups of fast path extensions.
Made babl mostly threadsafe (sufficient for GIMP/GEGLs needs). Streamlined
core functionality, reducing number of function calls and removing overeager
instrumentation.
Support for RGBA representation in the frequency domain,
un-pre-multiply close-to-zero alpha values to complete black instead
of slightly brighter than black, add a BABL_ALPHA_THRESHOLD constant
to the API, do a complete overhaul of the babl API and do some
changes to increase portability of the library.

babl is a dynamic, any to any, pixel format translation library.
It allows converting between different methods of storing pixels known
as pixel formats that have with different bitdepths and other data
representations, color models and component permutations.
A vocabulary to formulate new pixel formats from existing primitives is
provided as well as the framework to add new color models and data
types.
