Only do special handling of ob->data pointer in case we are remapping to
a valid (non-NULL) other obdata. Otherwise, handle it as any other
'remapping to NULL' case.
Hopefully not breaking anything else...
Move timer and tip out of button code,
now the only requests a tooltip,
passing a creation callback to run.
Needed for manipulators in 2.8,
also helps de-duplicate logic - since we never want
multiple tool-tips showing at once.
The issue was caused by Cycles allocating ID property in a temporary object
which gets overwritten and thrown away every so often.
Now dependency graph will try to reliably check whether ID properties from
a temp object are to be freed.
The issue here is that we can not duplicate the whole datablock since we
use view layer pointers in depsgraph callbacks.
Maybe this whole chunk of code belongs to somewhere else, or maybe we
can find a smart solution to avoid need of CoW pointers passed to the
evaluation functions.
This fixes lack of viewport update when toggling collection enabled flag.
This is similar to idproperty_reset() defined in layer.c, but it does not
re-alloc property itself.
We should replace idproperty_reset() with IDP_Reset() now.
Make sure scene and view_layer set for depsgraph before running editors
update. This is required since tagging might happen before we created depsgraph.
The issue was caused by some incompatibility of new API which expects ID block
to be specified explicitly, while old code is tagging object's data using
object's ID with OB_RECALC_DATA flag.
We need to switch all areas to give proper ID and everything, but for until
then we'd better stop crashing.
Compared to usual cddm one, ccgdm one was not applying the
ob->derivedDeform deformation to the pbvh generated from the
original mesh geometry, when possible.
We can only support painting from subsurf DM in a limited subset of
cases, others (like multiple subsurf, or topology-modyfying ones,
break mapping to original geometry).
This is not the most ideal fix (ideally, we should always be able to get
a mapping to original geometry from any point in modifiers stack...).
We do not always have that one available, and even without the
isDisabled callback this func is helpful.
Note that this is a bot stupid, only modifier actually needing a valid
Scene pointer here is subsurf... :|
It is possible to have animation (or driver) to modify nested datablock, such
as shape key value for example (where animation is on Mesh level, but shape key
is it's own datablock). To deal with such cases we need to create relation
from nested datablock CoW to animaiton/driver operation.
`gpu_texture_try_alloc` invalidates zero-sized textures.
The message in the console is not correct in this case (because it is not due to lack of memory).
Note this comes from the greasepencil-object branch, and are merged to help
preventing future merge conflicts.
Also, I renamed the icons for consistency sake. So when this is merged in 2.8
other areas of the code will need to change.

Previously only scalar displacement along the normal was supported,
now displacement can go in any direction. For backwards compatibility,
a Displacement node will be automatically inserted in existing files.
This will make it possible to support vector displacement maps in the
future. It's already possible to use them to some extent, but requires
a manual shader node setup. For tangent space maps the right tangent
may also not be available yet, depends on the map.

This converts object space height to world space displacement, to be
linked to the new vector displacement material output.

This was originally a good idea. However we will need to pay special attention
to this when doing the dynamic overrides anyways. The placeholders won't be
enough to spare us that job.
That said I left the ones on layer.c because we are actually calling these
BKE_override_*_add() functions from doversion, yet they don't do anything.
