For the boid Fight rule (and when determining friend/enemy health), we
need to check if other `ParticleTarget` psys is actually boids as well
(their health data is accessed -- which is only present on boid particle
systems), otherwise NULL data access crashes.
I know, EOL, but simple crash fixers should still get a chance to get in
I think.
Could also go into LTSes.

API: merged IMB_scalefastImBuf, IMB_scaleImBuf, IMB_scaleImBuf_threaded
into one function IMB_scale with enum IMBScaleFilter {Nearest, Bilinear, Box}
and bool "threaded" param.
Performance:
- Box filtering (nee IMB_scaleImBuf) can be multi-threaded now.
- Nearest filtering (nee IMB_scalefastImBuf) can be multi-threaded now.
Also fix performance regression on float images caused by fix in #126234
- Bilinear filtering (nee IMB_scaleImBuf_threaded) is several times faster now.
Correctness:
- Nearest and Box filtering: no longer loses half of edge pixels when scaling
up.
- Box: fixed garbage results (and possible out of bounds reads) for non-4
channel float images.
- Bilinear: no longer shifts image when scaling up.
- Bilinear: properly filters when scaling down by 2x2.
Test coverage:
- Add gtest coverage for various IMB_scale modes.
- Add a IMB_performance_test performance test, ran manually.

when tracing shadow ray through a volume and no hit is registered, we
consider the whole ray segment inside the volume.
However, no hit registered could also happen when the volume is
invisible to shadow ray. We should explicitly check this case and skip
rendering the volume segment instead.

This PR implements #126353; In short: keep discard list as part of swap chain images. This allows
better determination when resources are actually not in use anymore.
## Resource pool
Resource pools keep track of the resources for a swap chain image.
In Blender this is a bit more complicated due to the way GPUContext work. A single thread can have
multiple contexts. Some of them have a swap chain (GHOST Window) other don't (draw manager). The
resource pool should be shared between the contexts running on the same thread.
When opening multiple windows there are also multiple swap chains to consider.
### Discard pile
Resource handles that are deleted and stored in the discard pile. When we are sure that these
resources are not used on the GPU anymore these are destroyed.
### Reusable resources
There are other resources as well like:
- Descriptor sets
- Descriptor pools
## Open issues
There are some limitations that require future PRs to fix including:
- Background rendering
- Handling multiple windows
- Improve CPU/GPU synchronization
- Reuse staging buffers

Not sure why, but today I got almost systematic deadlocks in the
ProcessPoolExecutor calls (and similar issues with direct usage of
multiprocessing)... For now synchronous single process will do.
The `drawing_index` in frame data can become invalid during transform if
a frame overwrites another. This is very difficult to keep track of
explicitly, so instead this fix just "freezes" drawing indices by adding
a user at the beginning of the transform to every existing drawing and
removing it at the end after all frame data has been updated.
No `drawing_index` needs to be updated during the transform.

This adds the Eyedropper tool to GPv3.
A few changes have been made:
- Added `Brush` mode.
- Set active color in palette.
- Show the palette in the UI.
- Add UI for setting material mode.
- Drag for color accumulation.

On Legacy AMD devices EEVEE doesn't render any geometry. During testing
we found that it was based on reading normal attribute. Further testing
it was detected that enabling the high quality normals would solve the
rendering.
This is a known issue on legacy AMD drivers. This PR updates the check
to enable the high quality normals workaround for the latest known AMD
legacy drivers (22.6.1/21.Q1.2). Both drivers still have this issue.

#125625 moved the File Browser Thumbnail type icon location from the
bottom-left of the thumbnail extent to the bottom-left of the item
bounds. This does the same for the indication of offline and for
shortcut. This adds a new icon for shortcut instead of current use of
ICON_LOOP_FORWARDS, which doesn't look right. The new icon looks like
the Mac Alias arrow, but this also works fine for other platforms.

This reverts commit 93054f9a0e.
I had forgotten the reason for this separate "restore" step before the brush
deform evaluation was because multiple symmetry steps can be processed in the
same BVH node, in which case we can't just overwrite the values from the last
symmetry step.
Fixes#126445.

This adds initial support for showing the difference between old and new coverage
data. The difference is only shown in index.html currently. This is mainly useful
when adding new tests right now, to see the impact.
To use this, rename the `coverage/analysis` folder in the build directory to
`reference`. It will automatically be used by the report script if that reference
folder exists.
This PR moves new area space subtype update to ED_area_newspace so that
it is applied right after a new space is initialized. This is currently
done in rna_Area_ui_type_update, but after rna_Area_type_update.
Without the subtype set this can result in an incorrect titling of
single-area windows.

This increases playback performance from 2.9fps to 3.2fps in the test file from #126391.
The check is unnecessary in draw code, because we know that the depsgraph
finished evaluation before. These checks were introduced to handle dependency
cycles during depsgraph evaluation.
At some point it may be nice to look into making these checks cheaper to avoid having
to use the unchecked version for performance reasons.

This increases the hit size for the zone that allows resizing editors.
By approximately one more pixel on each side. This should make sizing
a little bit easier, especially with pens. Corner zone and region
reveal zone take precedence so I haven't found any time this causes any
interference.

This introduces `MemoryCount` which can be used across multiple
`MemoryCounter`. Generally, `MemoryCount` is expected to live
longer (e.g. over the entire life-time of a cache), while `MemoryCounter`
is expected to only exists when actually counting the memory.
When the preserve_all_data_layers argument was passed, the object
would be reevaluated, assuming the type of the original object data.
However, the evaluated object type can change compared to the
original, so to reevaluate the original mesh we need to check that
the original object was also a mesh object.

The issue was that the code path for layered actions never hit the
function `remap_cyclic_keyframe_location`.
The solution is to move that logic into `insert_vert_fcurve`.
My reason for why this is the correct solution is that
the remapping happens on a per FCurve basis, so it should be within `fcurve.cc`.
Doing so ensures that the layered actions also hit that code.
