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.

Added cache of profiled conversions, added HCY color model, some precision and
performance updated for fast paths.
2016-11-05 babl-0.1.20

Build improvements, remove blatantly wrong conversions from extensions,
made it possible to distinguish format_n formats from others, improvements
to vala/gobject introspection support.
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.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
1.) Pull in patch from GNOME SVN to get definition of "gzize" in the
Mac OS X specific part o "babl-cpuaccel.c".
2.) Fix broken build of extensions which need to be built as bundles
and not shared libraries.
This fixes PR pkg/40473.

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.
