When generating a preview image for a pose, temporarily apply it to the
armature. Contrary to the usual pose application, this ignores the
selected bones and always applies the entire pose.
This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,
etc.

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.
There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.
Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading
Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.
Patch implemented by Sergey and me.

This patch makes the "Render" window a top-level window, not a child of
the main window, which was the case in blender versions prior to 2.93.
This means it is no longer "on top", nor is the icon grouped on the
taskbar in the same way, but you can Alt-Tab between it and the main
window. This change only affects the Windows platform as the other
platforms behave this way.

Note that these changes are limited simple cases as these kinds of
changes could allow for errors when refactoring code when the known
state is not so obvious.
Under some circumstances using task isolation can cause deadlocks.
Previously, our task pool implementation would run all tasks in an
isolated region. Now using task isolation is optional and can be
turned on/off for individual task pools.
Task pools that spawn new tasks recursively should never enable
task isolation. There is a new check that finds these cases at runtime.
Right now this check is disabled, so that this commit is a pure refactor.
It will be enabled in an upcoming commit.

Textures may be important to be able to identify an object. They are also a way
to make many objects look more like when rendered with an advanced render
engine, without being that expensive.
So this seems like a simple way to increase usefulness of the automatic
previews.
Object orientation for thumbnail creation changed to be slightly
oblique (tilted to one side and from above) to better show shape,
especially when axis-aligned. Camera lens changed to 85 to avoid
distortion of close objects like human heads.

Pass `bContext *C` a bit further down the call stack, to prevent
exploding the number of parameters of `ED_preview_icon_render()`. An
upcoming change will require access to yet another context member, and
this can now be done without adding yet another parameter.
No functional changes.
For Cycles, when enabling the Persistent Data option, the full render data
will be preserved from frame-to-frame in animation renders and between
re-renders of the scene. This means that any modifier evaluation, BVH
building, OpenGL vertex buffer uploads, etc, can be done only once for
unchanged objects. This comes at an increased memory cost.
Previously there option was named Persistent Images and had a more limited
impact on render time and memory.
When using multiple view layers, only data from a single view layer is
preserved to keep memory usage somewhat under control. However objects
shared between view layers are preserved, and so this can speedup such
renders as well, even single frame renders.
For Eevee and Workbench this option is not available, however these engines
will now always reuse the depsgraph for animation and multiple view layers.
This can significantly speed up rendering.
These engines do not support sharing the depsgraph between re-renders, due
to technical issues regarding OpenGL contexts. Support for this could be added
if those are solved, see the code comments for details.
It looks like we never generated correct icon previews for images with
float_rects (non-8bit-images). Images from the report were 16bit pngs.
In this case, `icon_preview_startjob` would return early (it only
checked if the ImBuf `rect` was NULL -- which is the case if it has a
`rect_float` instead). This is not neccessary since `icon_copy_rect` is
perfectly capable of taking float rects.
Now correct the check and only return early if both `rect` & `rect_float`
are NULL.
note: this will not refresh icon previews from existing files
automatically. For this, use File > Data Previews > Clear Data-Block
Previews.

Render previews for Action datablocks by rendering the scene camera with
the Workbench (solid) engine. The //look// can be configured by setting
the scene's render engine to Workbench and editing the scene's shading
properties.
It is assumed that the pose has already been applied and that the scene
camera is capturing the pose. In other words, the render function just
renders from the scene camera without evaluating/applying the Action
stored in `preview->id`. The ID is only used to determine its type and
to store the resulting preview.
Not all code paths that lead to the `action_preview_render()` function
actually provide a depsgraph. The "Refresh Asset Preview" button
(`ED_OT_lib_id_generate_preview`) does, but `WM_OT_previews_ensure` does
not.

In 2.81 there was a change to increase the performance of viewport
animation rendering. This change would perform the color management on the
GPU if the only 8bit was needed. This saved CPU cycles and data
transfer.
The issue is that in the image editor or when saving the image the CM
will be reapplied. Although the speed is desired, exporting the actual
colors has more priority.
In the ticket there is an analysis that shows that shows that this fix
is the correct short term step to take. It would be better that the
render result is aware of the color space of its buffers so the applying
color management could be skipped when saving to disk or drawing in the
image editor.
The issue with this change is the performance penalty it has.

Preview icons (e.g. material preview or other data-block previews) use the same
background-job code as deferred loading of custom icons/previews. There was a
check to skip preview generation if the render engine does not support preview
rendering mode, which workbench doesn't. However this check should only be used
when actually rendering a preview, not when doing deferred loading.

Removing the user count and fake user count icons was controversial (which was
expected) and there are a few further changes needed, that won't make it in
time for the release, see D9946.
While there is a design to bring back the user count and fake user indicators,
a new design idea was proposed that the UI team wants to follow. This came too
late for the 2.92 release, the new design is targeted at the 2.93 release now.
Meanwhile, UI team decision was to simply revert the design changes.
The new design is being worked on in https://developer.blender.org/T84669.
Note that this commit does not revert some internal changes done in
2250b5cefe. Namely the introduction of `ed_util_ops.c` and data-block
operators in there. These will still be needed in the new design.

The previous design is rather old and has a couple of problems:
* Scalability: The current solution of adding little icon buttons next to the
data-block name field doesn't scale well. It only works if there's a small
number of operations. We need to be able to place more items there for better
data-block management. Especially with the introduction of library overrides.
* Discoverability: It's not obvious what some of the icons do. They appear and
disappear, but it's not obvious why some are available at times and others
not.
* Unclear Status: Currently their library status (linked, indirectly linked,
broken link, library override) isn't really clear.
* Unusual behavior: Some of the icon buttons allow Shift or Ctrl clicking to
invoke alternative behaviors. This is not a usual pattern in Blender.
This patch does the following changes:
* Adds a menu to the right of the name button to access all kinds of operations
(create, delete, unlink, user management, library overrides, etc).
* Make good use of the "disabled hint" for tooltips, to explain why buttons are
disabled. The UI team wants to establish this as a good practise.
* Use superimposed icons for duplicate and unlink, rather than extra buttons
(uses less space, looks less distracting and is a nice + consistent design
language).
* Remove fake user and user count button, they are available from the menu now.
* Support tooltips for superimposed icons (committed mouse hover feedback to
master already).
* Slightly increase size of the name button - it was already a bit small
before, and the move from real buttons to superimposed icons reduces usable
space for the name itself.
* More clearly differentiate between duplicate and creating a new data-block.
The latter is only available in the menu.
* Display library status icon on the left (linked, missing library, overridden,
asset)
* Disables "Make Single User" button - in review we weren't sure if there are
good use-cases for it, so better to see if we can remove it.
Note that I do expect some aspects of this design to change still. I think some
changes are problematic, but others disagreed. I will open a feedback thread on
devtalk to see what others think.

This patch introduces a partial update of GPUTexture. When rendering
a large image the GPUTexture could have been scaled. The old implementation
would rescale the image on CPU and create a new GPUTexture. This
resulted in flooding the PCI bus.
The new solution would only scale and upload the parts of the GPUTexture
that has been changed. It does this by keeping track of areas of 256x256
pixels. When something changes the tiles that cover that changes will be
rescaled and uploaded the next time the GPUTexture is requested.

* Support defining (not necessarily rendering) icons in threads. Needed so the
File Browser can expose file previews with an icon-id to scripts.
** For that, ported `icons.c` to C++, to be able to use scope based mutex locks
(cleaner & safer code). Had to do some cleanups and minor refactoring for
that.
* Added support for ImBuf icons, as a decent way for icons to hold the file
preview buffers.
* Tag previews as "unfinished" while they render in a thread, for the File
Browser to dynamically load previews as they get finished.
* Better handle cases where threaded preview generation is requested, but the
ID type doesn't support it (fallback to single threaded). This is for general
sanity of the code (as in, safety and cleanness)
* Enabled asset notifier for custom preview loading operator, was just disabled
because `NC_ASSET` wasn't defined in master yet.

Apparently the ID pointer can be NULL, which most code here assumes is
not the case. But it's very fragile & finicky, there is one code path
were it's allowed to be NULL.
Add necessary NULL-checks, an assert as sanity check and a comment to
note the possibility of NULL.
Object previews are really helpful for visual data-block selection, like asset
browsing. Having them be generative should also be quite handy and should work
well enough in many, if not most cases.
What this does is simple:
* Place the object (actually a deep copy of it, for thread safety) in a virtual
.blend into an empty scene/view-layer.
* Add a camera, point it towards the front of the object, assuming that means
pointing towards its +Y axis.
* Use "Camera Fit Frame to Selected" logic to put the object into frame.
* Create a threaded off-screen render.
Of course, such an automatic preview will not work in all situations. E.g. it
currently does a bad job capturing a single plane. We could add options for
more advanced automatic previews, but probably custom previews is more
important, which I committed already (812ea91842).
