Backported features from master:
AVIF export (when built with >= libheif 1.8.0)
High bit export
User can select save bit depth (8, 10, 12) during export
Minor fixes in import
Back-porting some of the features from master:
AVIF import (need libheif >= 1.8.0)
High bit (10/12) import
NCLX color profile import (link with lcms)
Metadata import (link with gexiv2)
This adds a blend mode for all known psp blend modes that were not
converted yet except for adjust.
I couldn't find any information about adjust and it's value of
255 suggests that it is not a normal blend mode.
(cherry picked from commit 19b261f3c6)
Reduce number of undo steps created by Spryrogimp previews.
The implementation adds a function for clearing the
incremental preview drawing that is being executed as an idle task,
and closing an undo group in case the preview left it open (which
would usually be the case).
Traditional -config scripts are awkward for cross-compilation, multilib
systems (lib/lib64), and multiarch systems like Debian; only one copy
of the -config script can be in the PATH. As a result, some OS
distributions are starting to deprecate or even remove them.
pkg-config is designed to be a replacement for traditional -config
scripts, and is cross-compilation-friendly: the PKG_CHECK_MODULES macro
looks for an architecture-specific executable like
x86_64-linux-gnu-pkg-config, which can look in an architecture-specific
search path for library metadata, before falling back to a generic
pkg-config executable.
As a bonus, pkg-config also compares version numbers correctly
(see #2454).
libwmf having pkg-config metadata seems to be a relatively new thing,
so I've kept the -config script code path too, using it if pkg-config
does not find libwmf.
