GEGL 0.1.2
??????????
GEGL (Generic Graphics Library) is a graph based image processing framework.

GEGL provides a graph based API and framework to do demand driven, cached, non
destructive image editing of larger than RAM images. Through babl it provides
support for a wide range of color models and pixel storage formats for input
and output.

To build gegl-0.1.2 you will also need babl-0.1.2

Changes in this release
???????????????????????
• GeglLookup, configurable floating point lookup tables for lazy computation.
• Use GFileIOStream in GeglTileBackendFile.
• Optimizations: in-place processing for point filters/composers,
SIMD version of gegl:opacity, avoid making unneccesary sub-buffers,
removed some manual instrumentation from critical paths, improved
speed of samplers. In some cases with current GIMP this leads to a
doubling of the performance.
• Added xml composition/reference image based regression tests.
• Added performance tracking framework.
• Syntactic sugar using varargs for constructing gegl graphs from C.
• Build fixes on cygwin,
• Gegl# fixes.
• Initial, but unstable code towards multithreading.
• Improvements to lua op in workshop.
• Added new resamplers upsize, upsharp, upsmooth, downsize, downsharp and
downsmooth.
• Removed gegl:tonemap and gegl:normal ops.

This release of GEGL brought was brought to you by:
Martin Nordholts, Sven Neumann, Nils Philippsen, Adam Turcotte,
Danny Robson, Michael Schumacher, Ruben Vermeersch, Øyvind Kolås,
Javier Jardón, Yaakov Selkowitz and Michael Natterer, Kaja Liiv
