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.
This was fixed in master with commit 9d873fc3de. However, this fix never made it to 2.8.
(The following merge (a96008f3aa) did not import the fixes.)
Note: This fix is ment to fix the alignment problem.
I don't know if other parts of the code not merged are interesting or not.
But if they are, they should be tackled separately.

This optimisation only works if no material in the scene require the AO pass.
For this either set the AO distance to 0 or both Cavity and Edges factors to 0.
This double the performance of scenes with very high triangle count.
