[Gimp-developer] GEGL-0.3.12 and babl-0.1.24

[Øyvind Kolås <pippin gimp org>]

GEGL provides a node/graph based API and framework for cached, interactive
non-destructive image processing. GEGLs data flow image processing graphs are
used by GIMP and other software like gnome-photos, imgflo and iconographer.

Highlights of changes in this release:

Core:
 • less locale dependent serializations/parameters
 • fix local raw file detection of ARW and CR2 files
 • gegl_memset_pattern performance improvement
 • clean up the way we drop references and free memory
 • static caching of some frequently used babl formats/types.
 • mipmap preview render code fixes for the following subset of
operations: point
   operations (filter, and composer subclasses), integer translate, crop.

Operations:
• new ops: edge-neon, image-gradient, slic, wavelet-blur, waterpixels, watershed
• moved from workshop to common: color-warp, component-extract
• text: remove now unneeded work-around, ability to control vertical
   positioning, permit <1.0 font-sizes, handle text-color alpha, other
   improvements.
• lens-distortion: default to transparent background
• crop: bounding box computation simplifications
• noise-rgb: add gamma and distribution properties
• dither: renamed from color-reduction and improved ui/property controls.
• high-pass: do inversion, over and contrast in non-linear RGB
• noise-rgb: new linear and gaussian properties
• transform: added a clip-to-input property
• raw-load: improvements to handling of Sony's ARW files
• exposure: replaced offset with black-level
• moved from common to workshop: bilateral-filter-fast
• new workshop ops: bayer-matrix, linear-sinusoid,
 shadows-highlights, integral-image, segment-kmeans,
• removed ops: gaussian-blur-old

To build gegl-0.3.12 you will also need babl-0.1.24 which has recently been
released with various new performance short-cuts and profiling cache
improvements.
