2019-08-22 babl-0.1.72
Added handling for grayscale ICC profiles and gobject introspection support.
Optimizations for many format conversions for u8, u16 and half formats. And
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:

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.

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.
