Comprehensive rewrite of the DDS import routine, in the interest of
easier maintainability and readability. Adds formats.c/h, containing
tables and functions related to reading and parsing uncompressed files.
Importer now supports nearly all non-video uncompressed formats.
Includes a variety of minor-to-moderate fixes made along the way
which could not be pulled out into separate commits due to dependence
on other aspects of the rewrite.
Moves most of the code relating to YCoCg and Alpha Exponent into
misc.c/h, in the interest of making the rest of the codebase cleaner.
Removes the decode option from the import menu, as encoded files are
always decoded now (there used to be a menu button for doing this
after import, but with it gone there's no reason ever to not decode).
Finally, the remaining functions in color.c were only ever called once,
so these were extracted and inlined, and the empty file deleted.
Now that we bumped our meson requirement, meson is complaining about
several features now deprecated even in the minimum required meson
version:
s/meson.source_root/meson.project_source_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.source_root. use meson.project_source_root() or meson.global_source_root() instead.
s/meson.build_root/meson.project_build_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
Fixing using path() on xdg_email and python ExternalProgram variables:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
s/get_pkgconfig_variable *(\([^)]*\))/get_variable(pkgconfig: \1)/ to
fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': dependency.get_pkgconfig_variable. use dependency.get_variable(pkgconfig : ...) instead
This gives a big cleanup in the meson.build files of the plug-ins.
It's also quite a bit more maintainable, since anything that changes in
libgimp's dependencies, linkage, ... doesn't have to be copy-pasted into
each plug-in.
There were 2 warnings of unused functions on this file, and masking
them, we were ending with a whole file #ifdef-ed 0. So let's just get
rid of the whole useless file.
