"edit-paste-as-new-image-short" and "vectors-selection-to-vectors-short" were
just duplicate of the action named the same, except for the "-short" suffix, and
the only point was to have different labels.
Not though that this time, it was not enough to conclude that the action in a
menu shoud have the short variant. These were both used differently depending on
the menu.
Instead I added the concept of "label-variant" attribute in .ui menu files. When
the "long" variant is set, then we simply use the longer label.
There is still one more "-short" action: "tools-by-color-select-short", but I am
a still unsure how to handle this one.
Since we now generate actions for GEGL ops, we might as well generate menu items
for these too.
What I did:
- Move the "GEGL Operation…" tool (generic dialog with a drop-down list of all
non-ignored GEGL ops) to Tools menu.
- Create a "GEGL Operations" submenu in Filters > Generic.
- Move "GEGL Graph" to the top of this new submenu.
- Generate a new menu item for each generated action tied to a GEGL plug-in,
alphabetically sorted.
Depending on where it's used, this list of action can be either in the
"dockable" or the "dialogs" action group.
The meson rule is a bit more complicated than I wished it were because of the
ever-so-blocking lack of simple dependency in meson.
