We use 'reference' to designate the linked ID which is being overridden
by the local one, so using 'reference' to designate the stored local ID
in apply RNA code was... not a good idea. ;)
Actions shouldn't be copying by new library management code.
Or at least should be possible to make it to not copy actions
or do unneeded user management.
This way we avoid modification of original data which could
and does cause threading conflict with copy-on-write which
could be happening for viewport.
Skip access to any evaluated data when operator is run on file load,
we don't have depsgraph evaluated yet. In this case we skip part of
sculpt session initialization, since it will be done during depsgraph
evaluation which happens after DEG_on_visible_update().
We can not skip sculpt session initialization since during normal
operation we want all the data to be initialized on mode change,
and not on initial brush stroke.
This reduces the number of headers we need to import (and/or dependencies
on the order of them), as these depend on PBONE_VISIBLE(), which is already
in BKE_armature.h
Like the select/deselect operators, we only support doing this for the
active object for now. From the UI panels, it doesn't make sense to be
operating on bone groups which may not appear/line up with those in the panel
that we're currently dealing with.
This can be reviewed later, but for now, it's easier and makes more sense
this way.
This operator was only partially converted to multi-object editing,
as on one hand, it was using the new "objects in mode" iterator,
while on the other hand, it was also using the context iterator inside
that, making all selected bones across armatures get included.
We only want these to operate on the "active" armature only at a time
(where the "active" one is whichever the groups from the UI came from).
The fix therefore is to make it not use the context functions
(which were changed to always take bones from all selected armatures
instead).
Because:
- Less redundancy.
- Better suffixes.
Also a few modification to GPU_texture_create_* to simplify the API:
- make the format explicit to the texture creation process.
- remove the component count as it's specified in the GPUTextureFormat.
