GEGL-0.4.50 2024-11-03

Core:

• Better Gobject Introspection annotation coverage.
• Improved error handling for gegl chain processing.
• Added accessors for pad meta-data, to be able to show names and descriptions in UIs.

GeglColor: more lax parameters for g_arapm_values_cmp

Ops:

• API: GEGL_OP_NAME needs to be uniqe .c filenames no longer needs to be.
• First registered op with a given name now takes precedence over later.

• exr-save: store 16bpc files as half, fixing gimp
• ff-load, ff-save: fix build with FFmpeg 7
• dither: do processing in linear when all levels==2
• OpenCL: upgrade from 1.1 to 3.0, disable opencl caching system - not crashing is more important than caching. And fixes to the opencl operation of the following ops:
• alien-map
• color-to-alpha
• edge-sobel
• hue-chroma
• noise-reduction
• oilify
• snn-mean

New Ops:

• styles: a UI for achieving many visual effects for use on text and similar alpha defined shapes. bevel: simulate light and shadow on an alpha defined shape. inner-glow: an inner shadow glow effect

New Ops in workshop:

• ctx-script: an experimental op for rendering ctx protocol this might be a future basis for ctx-based vector layers.

Build:

• Various meson cleanups. Generate .pdb (CodeView) debug symbols for Windows Reproducible build fixed by getting rid of runtime values in .gir files.

Updated vendored libraries

• ctx has been updated from upstream, perhaps most significantly the protocol/drawing API has been fuzzed with afl+
