Object visibility is now handled by the depsgraph iterator, but this API
was incomplete as it made no distinction for visibility of the object itself,
particles and generated instances.
The depsgraph iterator API now includes information about which part of the
object is visible, and this is used by Cycles to replace the old custom logic.
Cycles and EEVEE visibility should now be consistent, which unfortunately does
means some subtle compatibility breakage for both.
Fixes T58956, T58202, T59284.

This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.
One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.
At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!

This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f0825.
Now the logic goes as:
- All pointers which we can not have shared (the ones which are
owned by the runtime) are cleared.
- The rest of runtime stays untouched.
This seems to be enough to keep particles happy.

Only back was possible.

- Clear deprecated flags for ID's:
Scene, Sequence, World, Object & Mesh.
- Clear deprecated flags for Spaces: outliner, 3D view & image.
- Remove unused `Mesh.drawflag`
- Remove unused `USER_ALLWINCODECS`, `USER_MMB_PASTE`.
- Remove `V3D_SOLID_TEX` & `V3D_ZBUF_SELECT` - used in a few areas.
- Flip `Object.empty_image_visibility_flag`
(avoids do-version on each new flag)
- Rename 'Backside' -> 'Back' in context of drawing - showing 'Back'
makes sense.

Helps separate variable names from descriptive text.
Was already used in some parts of the code,
double space and dashes were used elsewhere.
|
|
Also minor style cleanup.
|
|
Convert non-empty duplicators to empties.
|
|
Initialize to default values for meshes w/o vertices,
note that zeroing for BKE_object_boundbox_calc_from_mesh
matches old derived mesh code.

There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
|

|
|
Note: functions like select all are still not respecting that.
I will fix this as part of the local view commit though.

Previously each of the objects which has armature modifier will
request deformation matricies from bbones. Thing is, all those
deformations are the same and do not depend on object which is
being modified. What's even worse is that this calculation is
not cheap.
This change makes it so bbones deformation is calculated once
and stored in the armature object. After this armature modifiers
simply use it.
With a rigs we've got here dependency graph evaluation time
goes down from 0.02 sec to 0.012 sec.
Possible further optimization is to make bbone deformation
calculated at the time when bone is calculated. This will avoid
an extra threaded loop over all bones.
|
|
Currently we never return CCGDM from the modifier stack,
so the optimization was doing pretty much nothing.
Removing it completely for now, it needs to be re-done
with the new evaluated Mesh/Subdiv.

Same fix as for smoke (and is what caching proposal is AFAIK):
share cache between copied and original objects.
One thing which is still missing to be fixed is to make auto-cache
more reliable. It was already kind of broken, so don't think it
should be a stopping factor for this fix.
|
|
Selection should be separated from active state and handled by higher
level code (operators/editors) instead of happening automatically.

Support for showing images in background/foreground and only in perspective/orthographic view.
Internally the depth of the image is modified in the fragment shader by setting `gl_FragDepth` explicitly.
The UI still needs some work to improve usability, see D3863 for details.
Currently there is one duplicated function, not sure how to best deduplicate it yet. (`is_image_empty_visible`)

Full redesign of the cache system used for drawing strokes and handle derived frame data.
Before, the cache was saved in bGPdata and a hash was used to manage several objects with the same datablock.
Old design made the use of particles very inefficient and prone to bugs and segment faults, and especially when this was mixed with onion skinning and multiple objects using same datablock. Also, there were some conflicts with the depsgrah logic (the old design was done before despgraph was in place) that made the use of hash not working.
The new design saves the data in the object runtime struct and avoid the use of any hash to find the right data. This improves the speed and reduce a lot the complexity of the code, memory allocation, hash overload and adds full support for particles and reused datablocks.
The particles can reuse the modifiers and shader effects of the original grease pencil object.

Fixes edit-mesh not having a boundbox calculated for it.
|
|
The exception is for subdivision surface which still uses derived mesh.
|
|
|
|
DerivedMesh is now removed from edit-mesh modifier evaluation.
|
|
Also use const qualifier for object's.
|
|
Apparently, part of code got lost last minute prior to push.
|
|
As the comment states, this is not really great solution, but
is good enough for now. Proper solution needs some more work,
and maybe reconsideration of what is stored where.

The grease pencil does not need a toggle of mode.
This fix also the problem when open grease pencil files that did not keep the mode saved.
|

Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
