Build

• Drop autotools, GEGL is now using meson, most things are working again now - documentation/website build is a work in progress, many issues have been fixed, more a sure to surface with this first meson only release following the babl one.

Core

• Support ui labels and descriptions for aux pads of ops.
• Guard against uint32_t overflows in memory computations, improved memory usage stat on FreeBSD.
• Added support for hygon dhyana architecture.
• Added gegl_try_malloc and use it to allocate storage for tiles.
• gegl-stats gained active- and assigned-threads members.

Buffer

• New API for aligning to regular tile grid, gegl_rectangle_align[_to_buffer]
• added gegl_rectangle_xor
• gegl_buffer_create_sub_bufer now always returns a new object.
• Improved tile compression, more accurate accounting and avoidiance when it is determinetal.
• gegl_buffer_save : store BablSpace
• take into consideration concurrent use of different tile sizes in gegl_tile_alloc
• Fast path for gegl_buffer_copy is entirely in abyss.
• Improved api misuse handling in gegl_buffer_set|get
• Improved consistency of results when doing COW of abyss.
• Improved Gobject Intospection annotations.
• Use a binary tree for tile swap, improving tile removal speed.
• Avoid gegl_buffer_set avoid set_pixel fast path if level>0

Operations

• Dynamic computation of per-operation thread cost, making GEGL fully use available cores on more operations.

• new operations
  • bayer-matrix, linear-sinusoid, color-assimilation-grid, normal-map.

new operations in workshop:
  boxblur, alpha-inpaint

pass-through for infinite planes for:
  apply-lens, polar-coordinates, whirl-pinch, convolution-matrix, maze,
  cartoon, waterpixels, tile, distance-transform, spherize, tile-paper, dither,
  mantiuk06, reinhard05, fattal02, fractal-trace, motion-blur-zoom,
  motion-blur-circular, wind, little-planet, mirrors, cubism and long-shdow.
improved property ranges/meta-data or copyright for:
  motion-blur-zoom, edge-neon, cartoon, photocopy, softglow, oilify, bump-map, remap,

convolution: 
  fix source-buffer offsets of filtered-out components,
  avoiding excessive shifting.
jpg-save:
  force grayscale if incoming buffer is grayscale
sdl-display:
  port to SDL2
gamma:
  handle negative input values
apply-lens;
  enable auto threading
matting-global:
  disable auto threading, allocate less temporay memory.
maze:
  reimplemented without recursion
newsprint:
  added black pullout and per colorant pattern and period parameters, enable threading.
saturation:
  add a colormodel property which permits operating in RGB instead
of CIE Lab, enabling hue preserving saturation changes.
exr-load/exr-save:
  only use associated alpha with EXR files
ff-load:
  fix audio track decoding for pure audio files
c2g:
  fixed initialization data race and out of bounds array access when threaded.
color-enhance:
  fixed a buffer leak
perlin-noise:
  fix initialization race
domain-transform:
  faster nop for edge-preservation=1.0, support BablSpace
oilify:
  support specifying mask-radius with aux buffer
linear-gradient, readial-gradient:
  use colors in correct order.
pixelize:
  avoid potential glitches
weighted-blend:
  harmonize opencl implementation with C
edge-neon:
  performane improvements

GEGL UI

• gcut video editor ui has been removed, all its functionality is latent in the new media browser/manipulator/viewer UI.

• Permit start/end times for playlist items, enabling use of folder as EDL.
• Add ability loop currently shown media element.
• Nearest neighbor decoding; for realtime playback of HD video content.
• Frame-cache for rendered video frames (with associated PCM data)
• Drag and drop from file-managers to collection view.
