Previously settings were removed, now add to the rigid body world automatically
even if it's a bit ill defined, since this is confusing for users.
Fundamentally the concept of a rigid body world collection could be revised, and
left only as an optional thing.
This reverts commit 36faf739a7.
Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.
Since this change was not sufficient to get original report fixed
is easier to simply revert for now.

Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.
Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

Was noticeable when sequencer uses scene with a compositor.
The way it was using render API was forcing a single render layer.

Now, when you add an slot and then draw, the automatic created material will use the empty slot, instead to add a new slot and leave a empty one.
This fix only works if you add only an empty slot. We could remove any empty slot in the middle, but as this has no impact in the drawing or file, it does not worth the CPU time to review every time the material list. Anyway, the user can press delete button to remove any empty slot.
If we see this is a big problem in the future, we can reopen the bug and add this cleaning function.
The PBVHs raycast function calls `isect_ray_tri_epsilon_v3` with epsilon `0.1` which is inaccurate and may result in the problem presented in T65620.
The solution is to use `isect_ray_tri_watertight_v3` instead `isect_ray_tri_epsilon_v3`.
This can positively affect other areas as well.

Part of the issue was caused by missing speaker objects in the depsgraph
used for post-processing.
Remaining part was caused by missing scene sound update for this depsgraph.
Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
- MPEG4/DivX has a maximum value of 65535 for the timebase denominator.
- MPEG1 and 2 have a list of supported frame rate ratios. These use
ratios like 24000/1001 and need those exact numbers.
This fixes an issue introduced in c5b1e7cd4e
where the correct ratio was passed to FFmpeg, but not with the identical
numbers FFmpeg has in a lookup table.
Always compute CD_ORCO undeformed coordinates now for rendering, same as before.
There is still a refresh issue to be fixed, when switching from solid to textured
mode in the viewport.
Computing such undeformed coordinates can be expensive and is not actually needed
if the mesh is only using e.g. UV maps. This was the same in 2.79, at least now we
are skipping the computation when there are no deforming mdifiers on the mesh.
This saves memory and evaluation time for simple static meshes with e.g. a
subdivision surface modifier. If no CD_ORCO layer exists then we assume the
actual vertex coordinates are equal to the original undeformed coordinates.
While user should never do that, it appears many end up using a 'view
layer' instancing collection as RBW collection, and even worse, have
objects in that unique collection.
Therefore, when removing RB simulation from an object, which among other
things has to remove it from the RBW collection, it would fully delete
the object from the blend file.
This fix merely checks the usercount of RB-removed object, and if it is
at 1 (which means object was in a single collection), it adds it to the
scene's master collection first.
Allows it to be preserved during copy-on-write update when on-geometry
related update is needed.
This is a required part for T63537, where we need to preserve the entire
evaluation data when object is tagged for only RECALC_COPY_ON_WRITE.

This was a design decision, but now we have decided to change it using the active material for the strokes using deleted material.
If the material slot is empty a new material is created to keep the strokes visible.
Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.
Also added several missing strings (including the one reported in D5056
by Jean First (@robbott), thanks).
Collections are a tad annoying with all their caching of objects... When
we modify content of a children collection, we need to tag DeG for CoW
update of all of the ancestors.
For now keeping that recursive tagging helper private, but would not be
surprised if we found more similar cases and needed to expose it to more
code...
FFmpeg uses a fraction of integers to indicate the frame rate, whereas
Blender uses `int / float`. When a custom frame rate is used with
non-integer base, the FPS and Base settings were multiplied with 100000
before passing to FFmpeg as `int`. This could overflow when a high
enough FPS setting was used, which is the case when importing a video of
almost-but-not-quite-integer frame rate into the VSE. The overflow
caused FFmpeg to return an error "The encoder timebase is not set",
which is rather cryptic for users.
The new solution is to take the max int and divide that by the frame
rate, and use that ratio to pass to FFmpeg. This won't overflow, and
thus allows exporting arbitrary frame rates.
A lot of areas were querying sound information directly using audio handle
which does not exist on an original sound IDs.
This change basically makes it so it's possible to query information about
given sound ID, without worrying about whether it's loaded or not: if it is
needed to load it first it happens automatically (no automatically-opened
handles are left behind though).
While this seems a bit extreme to open files on such queries it is still
better than the old situation when all sound handles were opened on file
load, no matter if it's needed or not. Besides, none of the changed code
paths are performance critical, just handful of tools.

How to reproduce: use 1-10 to change the visible collection. If the
collection was globally invisible, it would be set to globally visible.
This was a left over from the previous collection visibility design.
Now that we have a more clear separation between temporary visibility
(i.e., layer collection visibiilty) and a global visibility setting
(i.e., collection visibility) we should keep them separated.
Most of the time this actually tags evaluated mesh which will be tossed
away few lines below anyway. And this causes issues if the evaluated
mesh is actually owned by the mesh datablock.
The bounding box now has clear separation between original object data
and object data after modifiers, so this should not be causing any
issues.
