gegl: update to 0.4.50.

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#10778

  * 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+
