Preview render depsgraphs are put in the depsgraph registry
concurrently with other threads. This was lacking a mutex lock
and a map value that remains unchanged when other elements of
the map are updated.

When an object has no UV layers and an anonymous UV layer is created,
the anonymous layer gets set as the default (render) layer. This is
very confusing because it then uses a hidden anonmous layer. This patch
suppresses the usage of anonymous layers for rendering.

`scissor_test_set` wasn't able to parse the arguments that were
passed correctly, due to incorrect control data during functino
registration.
This patch uses the correct control data during registration and
is able to parse arguments.

Auto-depth is no longer reset during consecutive touch-pad motion.
Details:
- Add wmEvent::flag, WM_EVENT_IS_CONSECUTIVE to detect consecutive
track-pad & NDOF motion events. Expose via RNA as Event.is_consecutive.
- Consecutive events are broken by button/key presses and mouse motion.
- Add `WM_event_consecutive_data_*` functions, so operators can store
data between consecutive events.
- Add `ED_view3d_autodist_last_*` functions to access the last autodist
pivot point for view operators to use.
This is an issue revealed by the recent optimization in 4d3bfb3f41 to have
CPU and GPU subdivision topology both cached.
BKE_subsurf_modifier_subdiv_descriptor_ensure is what (re)creates the
topology refiner when needed. Invalidating the topology refiner on changes
must be done before it, otherwise we end up with an incomplete Subdiv that
either does not draw or draws incorrectly.

This makes it possible to use `Vector` recursively if the inline buffer
has 0 size. Any other inline buffer size does not work, because then
the type would be embedded in itself which does not make sense.

Various UI code would store the `AssetHandle` in a way that turns out to
be unsafe. The file-data is part of the file browser caching system that
releases file-data when a certain maximum of items is in the cache. So
even while just iterating over the assets, earlier iterated asset
handles may become invalid. Now asset handles are really treated as
volatile, short lived objects.
For the asset-view, the fix was more involved. There we need an RNA
collection of asset-handles, because the UI list code requires that. So
we create a dummy collection and get the asset handles as needed by
index. This again meant that I had to keep the index of the collection
and the asset-list in sync, so all filtering had to be moved to the UI
list.
I tried duplicating the file-data out of the cache instead, but that
caused problems with managing the memory/ownership of the preview
images.
`AssetHandle` should be removed and replaced by `AssetRepresentation`,
but this would be an even more disruptive change (breaking API
compatibility too).
Fixes#104305, #105535.

These are not really about reading or writing .blend files, they are
general utilities for file-names/paths. Having to link to the
blendloader library just for these utilities is annoying.
Moved them to `BKE_blendfile.h` now, in agreement with Bastien.

While this was just a single pixel off, it was a bit notable since the
highlight wasn't centered correctly. Now retina and non-retina screens match
visually.
Adds two modes of GPU frame capture support for
enhanced debugging. GPU frame capture begin/end
allow instantaneous frame capture of all GPU commands
within the capture boundary.
GPU frame capture scopes allow several user-defined capture
regions which can wrap key parts of code. These scopes are
exposed to connected GPU tools allowing the user to manually
trigger a capture of a known scope at the desired time.
This is currently integrated with the Metal backend for
support with Xcode.

Fix race condition if several competing threads are inserting Metal
buffers into the MTLSafeFreeList simultaneously while a new list
chunk is being created.
Also raise the limit for an MTLSafeFreeListChunk size to optimize
for interactivity when releasing lots of memory simultaneously.

Optimized node graphs do not get cached and were
not correctly freed once their reference count reached
zero, due to being excluded from the GPUPass garbage
collection.
Also suppress Metal shader warnings, which are prevalent
during material optimization.

Metal buffer binding validation would trigger an error
when a given shader had an empty PushConstantBlock.
This patch removes the default uniform code gen if
no uniforms are present, to avoid any possible issues
with buffers being bound to a shader where the destination
data block is size zero.

Crash when selecting objects on AMD platforms running
Metal. This was caused by shader compilation warnings
being treated as errors in macOS 10.15. Wrapping
compilation failure with success check resolves error.

immDrawPixels performs significantly slower in Metal
than OpenGL. This was caused by two main factors. Firstly,
the additional overhead of tiled texture update, where all
memory needed to be kept in flight for each update, but
caused update to take a slow path. Avoiding tile update
with Metal is more efficient for both memory pressure
and GPU pipelining.
Secondly, on AMD platforms, the staging buffer used
for temporary texture data was page-faulting when
several texture updates would occur within one frame.
This is due to limitations of allocating one large contiguous
memory chunk. Using the Metal buffer pool for staging
data is more efficient.

Maximum distance of lines in screen space is limited. This limit seems
reasonable for FPS higher than 1, but UI allows to set 0.01 FPS with
soft. even lower values are possible.
This patch allows for normal operation within soft limits and labels are
still visible and quite usable within hard limits.

Without assumptions of a mesh's direct ownership of its normals,
this was error prone, since normals could potentially be reallocated
when they are tagged dirty or retrieved with write access.
- Show/hide mask layers: the tooltip was confusing from a user's
perspective, because they should not be expected to know what a hide
flag is.
- Active Spline -> Active Point: likely a copy and paste error.
- Geo Nodes face is planar node: forgotten article.
- Axes, plural instead of axis for the viewport preferences. Here
there are several usages of axis or axes. Since they refer to
coordinate axes I believe they should be plural, even though the
property `mini_axis_type` is still wrong.
