Changelog:
2020-06-07 babl-0.1.78
Bugfix release - mutex and atomicity related issues.
2020-05-27 babl-0.1.76
Wrap hue in HSV, HSL, HCY. Fix black pullout in non ICC CMYK
conversion. Added AV2 gamme u8->linear float conversions. VAPI file generation
for vala integration. Adjusted strategy for conversion selection, trades back
warm-up time for missing some fast multi-step conversions.
Babl v0.1.74 now uses .dylib as the extension for modules on Darwin.
Consequently, it is no longer necessary to rename the files post-install,
but it is necessary to use different extensions for more of PLIST.
The previous patch removed use of --version-script on Darwin and converted
the shared library extensions to the Darwin standard of .dylib. The former
is necessary, but the latter was not quite correct. A distinction must be
made between shared libraries provided by the package for linking of
applications and shared libraries provided by the package for dynamic loading
by Gnome applications. Gnome applications expect that plugins will use the
.so extension on all Unix platforms, including Darwin. Thus, a subset of the
shared libraries must be renamed, both on the filesystem and internally.
This is partly mentioned in PR #54824, although that is for graphics/gegl
not tnis package.
Build fix for older compilers with c89 default...
../babl/base/formats.c: In function 'babl_formats_init':
../babl/base/formats.c:38:3: error: 'for' loop initial declarations are only allowed in C99 mode
2019-08-22 babl-0.1.72
Added handling for grayscale ICC profiles and gobject introspection support.

fixed a crash for NANs in float to u8 conversions.
2019-08-02 babl-0.1.70
Build fixes making the meson build work with more architectures.
2019-07-25 babl-0.1.68
Added Yu'v' (CIE 1976 UCS) color model. Fixed a severe non-initialised memory
issue - that kept us from using fast paths for many babl spaces loaded from
profile. More fully symmetric conversions between associated and separate
alpha. Added more converters, both SSE2 and non-SSE2 for matrix-conversion
between different RGB spaces. Improvements to website/documentation; babl is
now using the terms associated alpha and separate alpha, all of:
nonpremultiplied-, premultiplied- and nonassociated- alpha are now considered
deprecated API. HCY luminance is now relative to the RGB space used - no change
for sRGB related pixel formats. AVX2 acceleration for some linear to float
conversions.
Changelog:
2019-06-12 babl-0.1.66
Added API call, babl_space_get_rgb_luminance,

is RGB, CMYK type of alpha and similar.

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.
