The issue was caused by image ID nodes not being in the depsgraph.
Now, tricky part: we only add nodes but do not add relations yet. Reasoning:
- It's currently important to only call editor's ID update callback to solve
the issue, without need to flush changes somewhere deeper.
- Adding relations might cause some unwanted updates, so will leave that for
a later investigation.
Animation system has separate fcurves for each of array elements and
dependency graph creates separate nodes for each of fcurve, This is
needed to keep granularity of updates, but causes issues because
animation system will actually write the whole array to property when
modifying single value (this is a limitation of RNA API).
Worked around by adding operation relation between array drivers
so we never write same array form multiple threads.
It was possible to have synchronization issues whe naccumulating smooth
normal to a vertex, causing shading artifacts during playback.
Bug found by Dalai, thanks!
They were not real issues, it's just some areas of code tried to create
relations between non-existing nodes without checking whether such
relations are really needed.
Now it should be easier to see real bugs printed.
Hopefully should be no regressions here.
Request from Hjalti Hjalmarsson for the animation work.
Basically a common part of the workflow of animation is to change the pose, scrub back and forth a few times and roll back the changes when unsatisfied.
However if you go back and forth too many times the UNDO stack would be full, and it would not be possible to bring back the previous pose.
I'm leaving clip_editor change frames as it is for now. But we can
probably change the behaviour there as well.
Issue here was that py API code was keeping references (pointers) to the
liniked data-blocks, which can actually be duplicated and then deleted
during the 'make local' process...
Would have like to find a better way than passing optional GHash to get
the oldid->newid mapping, but could not think of a better idea.
Radial append/remove had swapped args and *slightly* different behavior.
- bmesh_radial_append(edge, loop)
- bmesh_radial_loop_remove(loop, edge)
Match logic for append/remove,
Logic for the one case where the edge needs to be left untouched
has been moved to: `bmesh_radial_loop_unlink`.
This is yet another debug option that allows to render an arbitrary
simulation field by using a color ramp to inspect its voxel values.
Note that when using this, fire rendering is turned off.

This option allows to create a smoother transition between Bricks and Mortar - 0 applies no smoothing, and 1 smooths across the whole mortar width.
Mainly useful for displacement textures.
The new default value for the smoothing option is 0.1 to give some smoothing that helps with antialiasing, but existing nodes are loaded with smoothing 0 to preserve compatibility.

constraints.
This avoids traversing the archive everytime object data is needed and
gives an overall consistent ~2x speedup here with files containing
between 136 and 500 Alembic objects. Also this somewhat nicely de-
duplicates code between data creation (upon import) and data streaming
(modifiers and constraints).
The only worying part is what happens when a CacheFile is deleted and/or
has its path changed. For now, we traverse the whole scene and for each
object using the CacheFile we free the pointer and NULL-ify it (see
BKE_cachefile_clean), but at some point this should be re-considered and
make use of the dependency graph.
Issue was happening when removal of custom icons was done while they
were still being rendered by preview job.
Now add a 'deffered deletion' system, to prevent main thread to delete
preview image until loading thread is done with them.
Note that ideally, calling `ED_preview_kill_jobs()` on custom icon
removal would have been simpler, but we don't have easy access to
context here...
Rewrite the current range-tree API used by dyn-topo undo
to avoid inefficiencies from stdc++'s set use.
- every call to `take_any` (called for all verts & faces)
removed and added to the set.
- further range adjustment also took 2x btree edits.
This patch inlines a btree which is modified in-place,
so common resizing operations don't need to perform a remove & insert.
Ranges are stored in a list so `take_any` can access the first item
without a btree lookup.
Since range-tree isn't a bottleneck in sculpting, this only gives minor speedups.
Measured approx ~15% overall faster calculation for sculpting,
although this number time doesn't include GPU updates and depends on how
much edits fragment the range-tree.
Existing method was fine for basic polygons but didn't scale well
because its was checking all coordinates for every y-pixel.
Heres an optimized version.
Basic logic remains the same this just maintains an ordered list of intersections,
tracking in-out points, to avoid re-computing every row,
this means sorting is only done once when out of order segments are found,
the segments only need to be re-ordered if they cross each other.
Speedup isn't linear, test with full-screen complex lasso gave 11x speedup.
Do this for the new dependency graph: was missing handle of OB_UPDATE_TIME in tag update.
Hopefully it's all correct still.
Old dependency graph needs work, but i'm tempting to call it unsupported and move on
to 2.8 branch.
Material linking might and does change the way how drawObject is calculated
but does not tag drawObject for recalculation in any way.
Now use dependency graph to tag draw object for reclaculation. Currently do
this using OB_RECALC_DATA taq since tagging is not very granular yet. In the
future we can introduce ore granular tagging in the new dependency graph
easily.
Simple and safe for 2.78a.
Now, the strokes can be locked to a plane set in the cursor location.
This option allow the artist to rotate the view and draw keeping the
strokes flat over the surface. This option is similar to surface option
but doesn't need a object.
The option is only valid for 3D view and strokes in CURSOR mode.
When ED_screen_animation_play is called from wm_event_do_handlers,ScrArea *sa = CTX_wm_area(C); is NULL in ED_screen_animation_timer.
Informing the audio system in CTX_data_main_set, that a new Main has been set.
This would cause Alembic to throw an exception and fail exporting
animations because it was trying to recreate and overwrite the
attributes for each frame.
Also use the operator as part of the UI keymap now, to deduplicate code and let
users configure a custom shortcut.

It's mostly things where the signature in the .h and the actual implementation in the .c do not match. And a bunch functions who do not match the TaskRunFunction declaration cause they leave out the __restrict keyword.

Blender doesn't necessarily crash when Python doesn't keep references to
the returned strings. As a result, someone that implements this incorrectly
could be lulled into a false sense of correctness by Blender not crashing.
