This commit makes some tweaks that make it at least possible to use lib-linked
actions as Pose Libraries. Specifically:
* The apply poses button is no longer greyed out
* It is possible to select different poses from the list of poses
* All pose library operators which edit the poses stored in the poselib
now have improved poll callbacks which perform extra checks for lib-linked
actions (which cannot be edited, as all those changes will be lost)
Caveats:
* Due to the way the UI list template works, it doesn't seem to be possible to
make it not grey out the items in the list. (While the double-click to rename
thing shouldn't be allowed, items should at least look like they can be clicked on)
* The difference between clickable vs not-clickable isn't too great, making it hard
to tell that that while the Add/Remove/Sanitise toggles are not usable,
the Apply Poses is actually functional. But, this is a more of a UI-toolbox
level issue
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
We already had that for global keymaps (used e.g. to generate shortcuts for menu entries),
but this wasn’t possible for modal keymaps yet (e.g. help message in header during
transforms and other modal operation).
This commit only adds needing background code, it does not change anything from user PoV.
Modal operators will be updated to use it in comming weeks.
Thanks to Campbell for revisions & suggestions. :)
Differential Revision: https://developer.blender.org/D780
Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
Operators that trigger UI events (but nothing else)
were using 'CANCELLED' making it impossible to tell if an invoke
function failed, or opened a menu.
