Let's go with a simpler manifest since soon it will be built on a better
machine (our CI server) and to make scripts simpler.
Note that I also removed the old webkitgtk dependency, but actually I
realize the GNOME runtime does not have the new dependency as well,
since the runtime actually has a webkit2gtk-4.0 instead. We'll have to
look into this.
This flatpak is tested and working.
I have not yet verified though if it has the maximum options enabled
(guessing not), but only that we had at least the required dependencies
at least.
When we will merge, it will become the nightly flatpak and the current
nightly can be used to follow the 2.10 (future) branch.
This is the script I have been personally using for some time now to
build the devel and nightly flatpak on my server regularly through cron
files.
It is not the best script, arguably, and we can most likely do better.
But for now, it worked for me and is a first step toward maybe making
official nightly flatpak builds soon.
In particular a bunch of dependencies were moved to the BaseApp.
Dev flatpak is actually a bit useless now (since last dev release is
older than stable). But I keep the dev manifest around to make it easier
to update for the future when we'll have a new dev release.
Fix the registry path where uninstaller information is searched for
during installation, so that old GIMP versions are properly
uninstalled before installing a new version.
This fix has already been included in the 2.10.0 installer.
In order to bundle the MyPaint brushes, GIMP needs to be configured
with --enable-bundled-mypaint-brushes, and the brushes need to be
present at $GIMP_DIR32\share\mypaint-data.
