Add a default toolrc file, installed in the sysconf dir, with a
more minimalistic tool layout using groups, inspired by Photoshop
(not identical, though, don't kill me! :)
It must not be a boolean but a `feature` option, with `auto` by default.
`auto` value mean enabled for macOS and Win32, and disabled for other
cases. This default logics disappeared in the meson build.
Also the mypaint-brushes package is a mandatory dependency, which must
always be checked. Absence is fatale.
Finally properly set the MYPAINT_BRUSHES_DIR macro depending on the
proper relocatable case.
Some gimprc properties' default values depend on the machine where
"make dist" in run. We had an ugly hack in place to force
(num-processors 1) in the installed system gimprc and its manpage, but
were still leaking "tile-cache-size" and "mypaint-brush-path".
The files are generated by the hidden options --dump-gimprc-system
and --dump-gimprc-manpage which exist only for this purpose.
In gimpconfig-dump.c, special case the three properties in
dump_gimprc_system() and dump_gimprc_manpage() to output constant
default values for "num-processors" and "tile-cache-size" and
output @mypaint_brushes_dir@ in "mypaint-brush-path" which can
be replaced at configure time.
Also introduce etc/gimprc.in so @mypaint_brushes_dir@ can actually be
substituted for the installed system gimprc.
Since we have many themes now, this new name better indicates that it
is meant to follow your desktop theme settings.
Also it will likely not remain the default theme.
Don't hardcode modifier masks in the wheel and keyboard input
controllers. Instead, hardcode accelerator strings and get the right
modifier mask from gtk_accelerator_parse() at runtime.
This turns e.g. "<Shift><Primary>" into Shift+Cmd on OS X and into
Shift+Ctrl on X11 and Windows.
Also rename the events accordingly and change the event names in the
default controllerrc.
Unrelated: reorder the actions so the ones with less modifiers are
listed first, and change the order of action matching to match the
actions with most modifiers (the last ones) first.
Add support for a new type of Tab Style called 'Automatic'. This tab
style makes the GimpDockbook use the biggest actual tab style it can
for its auto tab style dockables, based on its widget allocation.
The tab style candidates for auto tab style are "Status + Blurb",
"Status + Text" and "Status". A docked widget can also say that it
wants to use "Icon" instead of "Status" for its auto tab style. The
'Tool Options' dockable does this. This is to be as backwards
compatible with the old tab style setup, we make 'automatic' the
default everywhere.
We have quite a bit of dependency to internal layout code in
GtkNotebook, but the current code should be pixel perfect and rather
complete.
Also add a basic regression test.
