This commit clamps the `brush->size` value to 1 at lowest for the
Grease Pencil Draw mode. There are situations where when the brush scene
space value is set to a small enough size that the distance calculated
by `project_brush_radius` becomes 0.
When this value is set as the actual brush size, the `wm.radial_control`
operator fails to work properly as the new size is now lower than the
expected minimum value, causing incorrect clamping of the modal value.

Drivers should perform a limit check when creating images and return
`VK_ERROR_OUT_OF_DEVICE_MEMORY`. However there are drivers where this
check is a pass-through and leads to `VK_ERROR_DEVICE_LOST`.
This issue was introduced !128877 and only shows up on official NVIDIA
drivers.

There is an issue in the GPU depth picking that is only visible
in official AMD/NVIDIA drivers. AMD does pick objects that are
around the cursor. NVIDIA drivers include any overlay objects.
This PR will disable GPU pick selection for AMD/NVIDIA official
drivers. This will limit some selection functionality.
This PR will be reverted in Blender 4.4 to find the root cause.

When using a lot of instances the requested and needed attributes
are merged. This process uses a lock even when no work needs to be
done.
By early exiting the merging process when no work needs to be done
the performance of navigating 60k cubes went from 17.5 fps to 18.3 fps.
Detected when researching #126391.

When opening the asset shelf brush selector popup in paint modes, clicking on a
catalog on the left wouldn't refresh the popup properly. Two catalog items
would be drawn as active, and the active catalog change wouldn't be reflected.
Only some mouse movements would trigger an update eventually.
Do copy asset data when copying an ID into the PartialWriteContext.
Currently there does not seem to be any use-case where this would not be
the desired behavior. This can be made an optional behavior in the
future if needed.
This lead to infinitely small return values from
`paint_space_stroke_spacing` (since the size can become so small) which
in turn causes an infinite loop in `paint_space_stroke`.
Was considering clamping to some other measure (e.g. based on bounding
box factors), but these might not work well in all circumstances
(dyntopo on a terrain-size mesh might still need tiny spacing), so
settled to clamp to the minimal numerical value.

This was caused by `drw_ResourceID` taking one vertex input
(at slot 15) which was then also used by material shaders.
Starting material shaders at 14 in this case avoid the overlap.
Note that this reduces the amount of supported attribute when
using the workarounds by one.
This commit adds a minimal, simple detection for future, incompatible
blendfiles (in case the header itself is modified).
The current available info does not allow to be more specific, but at
least this avoids telling users that it is not a blendfile.
In the future, the new header format designed in #129309 for Blender 5.0
should allow for a better report (since the first 16 bytes of the header
should always have the same meaning from there on).

The issue was that changing the area did not immediately update the
`snode->edittree` when changing between different node editor types. That update
only happened later in `node_area_refresh`. However, by that time, the `poll`
function of the modal operator has already succeeded even though when there
operator actually starts `poll` would not succeed anymore.

Caused by 2 issues:
- Incorrect logic when checking if added key matches last key
- FPS mismatch not compensated in `SEQ_retiming_key_speed_set()`
Also `seq_retiming_evaluate()` output was not clamped to 0-1 range. This
was not causing issues in sample .blend file, but output should be
clamped.

Mesh filter modes that use averaged neighbor data were not passing in
the mesh `hide_poly` attribute data, leading to incorrect behavior when
calculating averaged positions. To fix this and account for hidden
elements since we are operating on the entire mesh, we pass in the
attribute and use the `neighbor_data_average_mesh_check_loose` method to
account for vertices with no neighbors.

No idea why this was not reported before... Kind of critical info here.
Committed directly to 4.2 as:
* This is trivial change with extremely small risk of causing issues.
* Gold team at the studio needs it to better cleanup the production
files for publication.
Follow what was already done with the "reload" operator and tag the
Image ID during "replace".
A tag of "0" is used for now until we can investigate why the other more
appropriate values are not working.

This would happen if the viewport with large enough
and a tile resolution of 1:1 was choosen.
This changes the fallback behavior from simply clamping
the resolution (which did break a lot of math downstream),
to simply finding the next largest tile size that fits
the hardware requirements.
Crash manifested after the inclusion of #128877.
The very tall 3D texture tested by the new code
were not supported / tested by the Metal Backend.
Simply adding the appropriate upfront checks fixes
the issue.
Needs to be backported to 4.2
Adding a dummy storage buffer to the classification shader
seems to fix the issue on Qualcomm drivers (WoA).
The workaround is added to the force workaround option to
allow other platforms to test the fix.

Code used library reloading which would reload all data-blocks from a
data-block library. Since the essentials brushes are stored in a single
.blend file (one per mode), they would all be reset. In general this
violates the design where multiple brushes in a single .blend file
should be usable just fine. (A single file per brush is only necessary
to allow saving edits to that file without opening it.)
Instead of library reloading, delete the brush from the current file and
re-link it.
The link/append API should probably get support for reloading a single
data-block (and optionally its dependencies) but for now this is not
supported yet.

Some modifiers expect the curves to be of type `POLY`.
For such modifiers we need to resample the curves to the
evaluated points so that the modifiers work as expected.

The issue was that with a96f1208cc the clamping
of the `View2D` happened in the drawing function
of the channel list. That of course won't work if the
channel list isn't drawn.
The fix is to ALSO clamp in the drawing function of
the main area. The reason this has to be in addition, is that
(I think) the channel box is drawn first. So if the clamping doesn't
happen there, the channels and their keys can lose their vertical
alignment.

Armature::collection_array was indexed with -1,

This reverts commit 0a70360eb6. That's
because it caused issue #129366 which is much more serious, and the
cause is not obvious so far. Another fix will be submitted for the
original issue.
When using AMD official driver clearing depth attachments can fail.
I assume it is related to previous pipeline states and dynamic rendering
that don't require the correct pipeline state for clearing depth
attachments.

This was likely never an issue so far, as no ID type has ever been
removed (that was written in blendfiles at least), and no new BHead type
has been added since ages.
However, current behavior of the main loop in the readfile code (in
`blo_read_file_internal`) is to consider any BHead type which is not
explicitely known and handled, to be an ID BHead, and directly try to
load it as such.
This commit addresses that potential issue by validating that a BHead
code actually matches a known ID type before trying to use it to read an
ID from the file.
Issue identified while working on designs for future 5.0 forward
compatibility breaking changes in blendfile format itself.

Qualcomm driver can not handle the optimized SPIR-V that Blender
creates. According to their driver engineers this is an issue in
shaderc. As we are late in the release process they asked us to disable
the optimizations.
In Blender 4.4 we are planning to update shaderc what might fix the
issue. This should be retested after the update.
