Some RNA setters require ID data they operate on to be in G_MAIN.
Unfortunately, when we apply overrides as part of a .blend file reading,
new Main is not yet made global one, so we have to do it temporarily
here.
This is a fairly ugly hack, but it should be harmless and safe.
This is a first step towards supporting conversion of proxies, done
separately to make it easy to pinpoint in case it would create problems.
It is not expected to cause any change in behavior currently.
Constructive modifiers were not initializing an original index layer
in the case a previous deform modifier created 'mesh_final'.
This happened in the case of multiple deform modifiers that deform along
normals, as requesting normals caused the final mesh to be created.
Ensure mapping data is created in the case
only non-constructive modifiers have run.
Mainly a UI adjustment, no functional changes
To have the default mode in the advanced panel as separated option is not the best solution.
Now, there is a pin option and when it is enabled, the brush keeps this mode.

The problem is due to lack of precision with small and coplanar triangles.
Also, triangles that have vertices with the same coordinate are at the
threshold of the intersection.
We could add an epsilon to consider the minimum distance for intersection.
But that would add a lot of overhead to the code.
The solution used is to increase precision using doubles.
Some characters: `'`, `"`, and `\`, can cause problems with RNA paths.
Instead of using more complicated handling to deal with those cases,
we can just prevent these characters from being used in custom property
names.
This commit checks for these characters to `idp_try_read_name`, where
other checks like length are already done.

This refactor is in response to an unreported bug in which overlapping, moving colliders produced an unstable simulation.
Things that change apart from cleanup through this refactor:
- Effector objects with no velocities (either non-animated or animated but non-moving object) will explicitly set zero velocities in their flow bounding box.
- When applying object velocities to the global grid, they will now be accumulated per cell (add and not set velocities). Later they will be averaged with the object count at any cell.
Removed invel MAC grid since it is sufficient to use the cell centered vec3 representation. When setting initial velocities these will be interpolated by the setter functions.
With the new image editor drawing there were was some mutual exclusive
functionality. When rendering the alpha was shown correctly or the pure
emissive colors were shown correctly, but never both. The cause of this
is that the image_gpu did not used the correct alpha mode when generating
gpu textures for non-images (render results, compositors viewer)
The implementation always checked the alpha_mode. Alpha mode is an
attribute for images, but aren't set for non images. This patch adds
a more detailed check to ensure that the gpu texture is premultiplied.
The issue has been tested using several bug report files and production
files.

Since {D8234} the image editor is drawn using a depth buffer.
When using `draw_texture_2d` the image is drawn using the 2D_IMAGE
shader. inside the vertex buffer the image was pushed to the background.
This was introduced by {648924333234} what seems to be out dated as we
have done several overhauls in this area. (workbench refactor, overlay
engine refactor, color management pipeline).
This patch removes the pushing of the image to the background.
During viewport render animation the gpu textures weren't tagged as
invalid. As the image uv editor now draws the gpu texture only the first
was shown as it wasn't refreshed with the actual image data.
I created a bugreport T80859 earlier.
The problem is in the file source/blender/editors/sculpt_paint/paint_image_proj.c (line numbers against commit d376aea61)
at the lines 5309 and 5320 the functions `IMB_rect_from_float(...)` and `IMB_float_from_rect(...)` are called from threaded code on a shared ibuf.
However, ps->reproject_ibuf is shared between threads, so this is not thread-safe.
This is a race condition and leads to wrong output when projecting float data onto a uchar texture or vice versa on a multithreaded system.
The checks on line 5308 and 5319 are already a race condition.
I created this patch which fixes the problem , but I'm not sure if I'm overlooking something.
This makes sure reproject_ibuf contains the correct formats *before* the threadpool is started.
I replaced the original location of the conversions with BLI_asserts(). That may be overkill?

target in certain situations
Regression from rBdeaff945d0b96.
mesh_ensure_looptri_data would overflow.
Crash would only happen if a Data Transfer modifier (transferring
UVs) follows, so exact reason for this is not yet entirely clear. Also
there are edit-mode versions of the following BVH lookup functions so it
could be avoided (since this is a expensive operation), marking as TODO.
Similar fix as

This commit contains the Performance improvement, that was originally
proposed in D8966.
It improves the performance of the Weld Modifier by a lot.
It had a loop with execution time O(N^2) which is now O(N*log(N)) at a
bare maximum.
This patch adds a new operator to convert a black and white image into
grease pencil strokes.
If the image is not B/W, an internal conversion is done.
This is the first operator using Potrace, but we expect to add more features in next Blender versions.

The issue was two fold.
First something sets the loop element tag and doesn't clear it before
the UV code in question tries to use the tags. Added a sanity clear to
make sure that it operates on a clean tag state.
The next one was that the UV maps in question had quite a few points
that had zero length UV loop edges. This would lead to division by
zero.

It's generally considered a better codestyle to check conditions early
and exit early when they are not met, over having most logic of a
function within a big `if`-block. Otherwise people have to go over the
entire block to see if there's possibly an `else` somewhere, or any
followup logic.
There's the old and ugly hack where the `uiBut.poin` points to the
button itself. When reallocating the button we have to update that
pointer of course.
Those two functions had `BKE_` prefix, were defined in BKE headers, but
implemented in ED code, yuck.
Moved everything to ED area for now, since those do not look fondamental
enough to belong to BKE, and none of their usages requires it currently.
As noted by @lichtwerk (thanks), one can have a local object and/or
material using a linked image data-block, this case needs some different
handling to prevent painting on such linked image.
For now, tweak `BKE_paint_proj_mesh_data_check` (eeeek, that name
prefix!) to consider paintslots with linked image as 'non-existing'.
The function this was in already checks the conditions under which it
can operate (as it should). No need to force the caller to do these
(quite specific) checks, the function can just do nothing if the button
doesn't need these operations.
Otherwise we'd have to always execute these checks before calling, which
makes calling it a hassle, makes the code harder to follow and generally
harder to maintain (what if the conditions change?).
Allows scripters to store additional information in the marker itself instead
of using work-around approach based on marker names and such.

Originally was noticed when transforming mesh created by
object.to_mesh() from an object without modifier, in which case the
result references CustomData layers used by the object itself.
The issue goes a bit deeper: mesh.transform() should never modify
referenced layers, hence it should duplicate referenced layers.
This fix changes one specific aspect of the reported behavior. The
case where vertices coordinates are modified manually will still have
affect on the source mesh (as no referenced CustomData layers are being
duplicated). Proper fix for this case is not yet clear to me.

The issue was that the pointcache was not storing dead particles,
even though they are displayed. This lead to the rendering issue,
because only alive particles can be read from the point cache in
the frame that is rendered.
This also fixes an issue unrelated to rendering: when dead particles
are displayed, their position is incorrect when some frames are
skipped during playback.
