Removes the stutters comming from the film shader.
The number of samples used by the film shader is set
throught a specialization constant. Since the number of
effective sample can depend on jitter position, this
number was fluctuating and trigger compilation on
new specialization until all specialization were
encountered.
Rounding the samples up to the most common sample
count fixes the issue.

This caused UB in the tests now that tests are all ran
inside the same context.
A shader could be free but its pointer would be dangling
inside the `Context`. A new shader could have the same
address and generate UB after binding.
This is not the best way to solve this issue but at least
we prevent the use of the UB.

It's not common for object data to reference it's object type
so name the struct member to make this clear.
Also remove BKE_curve_type_get which is no longer needed.
- #122256: Clamp Size option did not work at all, due to mesh
bounding box still not being calculated (and was firing an assert
in Debug build).
- #123862: Clamp Size option was rounding the resulting scale to
powers of ten, which is not what anyone would expect.
This fixes both issues, and adds test coverage.

- Make Curve::type the source of truth for the curve type,
instead of Curve::vfont, since it's possible for this to be
set to null from RNA which effectively changed it's type.
See #138730.
- Update objects to match the curve type on file read.
Without this, an object may link to a curve in another file which
can be replaced by a curve data-block of a different type.
Note that updating the object type was already being done
when reloading library data and setting object data,
just not on file load.

The Path Template errors reported in tooltips could be incorrect,
depending on whether the field was visually truncated in the UI or not.
For example, if you had a path `/tmp/{blend_name}{foo`, the error is
that the template expression `{foo` is unclosed. However, if the
available space for the field in the UI is too small, the displayed path
could end up as `/tmp/{blend_na...`. This is for display purposes only,
and shouldn't effect things like template errors. However, it did, and
the error checking would be run on that display string, and report that
`{blend_na...` is unclosed, which is incorrect.
The issue was that the code doing the live error checking for the UI was
using the display string because it was conveniently available.
This fixes the issue by properly querying the property value via RNA,
and using that.

The variant of `RNA_property_string_get()` that returns a `std::string`
always returned a string with zero length. The issue is that it was only
calling `reserve()`, which ensures an underlying buffer with enough
*capacity*, but does not set the string length. The property's string
value would then be correctly copied to the reserved buffer, but the
string length would remain zero.
This commit fixes the issue by replacing the call to `reserve()` with a
call to `resize()`, which additionally sets the string length.

This adds the following options to Select Grouped in pose mode:
* Children
* Immediate Children
* Parents
* Siblings
Doing so means we are more in line with similar operators in edit mode.
Unfortunately re-using existing functionality from edit mode doesn't seem
possible due to the edit/pose bone difference.
The added functionality can handle multiple armatures in pose mode at once.
Also the same operators can be accessed from weight paint mode.

This patch adds a new Relative To Pixel node in the compositor. The node
converts values that are relative to the image size to values that are
in terms of pixels.
This is useful to use relative values in nodes that take pixel values.
For instance, the Kuwahara node has an input that defines the filter
size in pixels. If one wants to define it relative to the image size
instead, one can use this node.
The node can operate on float and 2D vector values. Further, the node
can do the conversion relative to a number of image properties:
- Per Dimension: Each dimension gets converted independently. The X
value is relative to the X dimension and the Y value is relative to
the Y dimension. This mode is special because in float mode, the
output will be a factor as opposed to a float.
- X: Relative to the x dimension.
- Y: Relative to the y dimension.
- Greater: Relative to the greater dimension.
- Smaller: Relative to the smaller dimension.
- Diagonal: Relative to the diagonal of the image.

Blender crashes when a node has a panel whose children input sockets are
all unavailable. This happens when marking sockets as collapsed, where
the non-initialized header_center_y members of such panels are accessed,
causing asserts or crashes.
The update_collapsed_sockets_recursive function has a check that should
avoid such accesses, but it seems wrong due to the negation of the
visibility check.
To fix this, we move the visibility check to a guard condition in the
marking function instead, and simplify the collapsed check in the update
function.

Calculating the curve type isn't needed for data which is only written
for text curves.
Note that this complicates a fix for #139133 which changes how curve
type data is accessed, where a version of BKE_curve_type_get that used
old behavior would have had to be kept for version patching.

This function to get the active attribute currently returns a custom
data layer pointer. This doesn't work when we transition to the new
`AttributeStorage` system. Returning an optional string is a simple
alternative that also aligns with the idea of changing the source of
truth from an index to a string stored on the geometry.

Add support for the UsdPrimvarReader_TYPE templates for both import and
export. These are used by several USD test assets and support here
represents the last major piece of the UsdPreviewSurface spec to be
implemented.
On import these become `Attribute` nodes and on export the `Attribute`
nodes will become `UsdPrimvarReader_TYPE`'s accordingly.
Import:
- `UsdPrimvarReader_float` and `UsdPrimvarReader_int` will use the `Fac`
output
- `UsdPrimvarReader_float3` and `UsdPrimvarReader_float4` will use the
`Color` output
- `UsdPrimvarReader_vector`, `UsdPrimvarReader_normal`, and
`UsdPrimvarReader_point` will use the `Vector` output
Export (only `Geometry` Attribute types are considered):
- `Fac` will use `UsdPrimvarReader_float`
- `Color` will use `UsdPrimvarReader_float3`
- `Vector` will use `UsdPrimvarReader_vector`
- `Alpha` is not considered
MaterialX note:
Hydra-native support is a bit more involved and will have to be done
separately. Hydra w/USD sync is trivial to implement but those changes
have been left out here.

This field's usage was removed with the brush assets project, previously
it was used during runtime in the `PAINT_OT_brush_select` operator.
This commit tags the DNA field as deprecated and marks the overall
`brush.cc` file with `#define DNA_DEPRECATED_ALLOW` to follow a similar
pattern as other BKE files dealing with I/O of ID types.
The field was added in 147b4b13ba and
updated in 7b7aba31f2 to prevent invalid
pointers from remaining on the brush.

This patch implements basic support for evaluating function nodes on volume
grids. Conceptually, a function node always creates a new grid for the output,
though the output is often a modified version of the input. The topology of the
output grid is a union of all the input grids.
All input grids have to have the same transform. Otherwise one has to use
resampling to make grids compatible.
Non-grid inputs are allowed to be single values or fields. The fields are
evaluated in a voxel/tile context, so they compute a value per voxel or per
tile.
One optimization is missing that will probably be key in the future: the ability
to merge multiple function nodes and execute them at the same time. Currently
the entire function evaluation is started and finished for every function node
that outputs a grid. This will add significant overhead in some situations.
Implementing this optimization requires some more changes outside of the scope
of this patch though. It's good to have something that works first.
Note: Not all function nodes are supported yet, because we don't have grid types
for all of them yet. Most notably, there are no color/float4 grids yet.
Implementing those properly is not super straight forward and may require some
more changes, because there isn't a 1-to-1 mapping between grid types and socket
types (a float4 grid may correspond to a color or vector socket later on).
Using grids with function nodes and fields can result in false positive warnings
in the UI currently. That's a limitation of our current socket type inferencing
and can be improved once we have better socket shape inferencing.

This adds a new Bit Math node which supports the following operations: `and`,
`or`, `xor`, `not`, `shift` and `rotate`.
For the `shift` and `rotate` operations, a posititive shift is a left shift and
a negative shift is a right shift.
Currently, the node always works on 32-bit integers which is what Geometry Nodes
uses internally for integers. If required, this can be extended to work on other
bit widths in the future.
The need for this came up every now and then. It can be useful when encoding
specific bits in integer attributes (for efficiency or because the geometry is
exported to other software that expects a certain format). Also, this node is
useful for some people doing crazy but fun things with Geometry Nodes like
emulating hardware. Even if the use-cases are not common, if they arise, it's
hard to work around and the cost of having this node is quite low for us.

This allows multiple threads to request different specializations without
locking usage of all specialized shaders program when a new specialization
is being compiled.
The specialization constants are bundled in a structure that is being
passed to the `Shader::bind()` method. The structure is owned by the
calling thread and only used by the `Shader::bind()`.
Only querying for the specialized shader (Map lookup) is locking the shader
usage.
The variant compilation is now also locking and ensured that
multiple thread trying to compile the same variant will never result
in race condition.
Note that this removes the `is_dirty` optimization. This can be added
back if this becomes a bottleneck in the future. Otherwise, the
performance impact is not noticeable.

Previously, whenever the zone detection algorithm could not find a result, zones
were just not drawn at all. This can be very confusing because it's not
necessarily obvious that something is wrong in this case.
Now, invalid zones and links that made them invalid have an error.
Note, we can't generally detect the "valid part" of zones when there are invalid
links, because it's ambiguous which links are valid. However, the solution here
is to remember the last valid zones, and to look at which links would invalidate
those. Since the zone-detection results in runtime-only data currently, the
error won't show when reopening the file for now.
Implementation wise, this works by keeping a potentially outdated version of the
last valid zones around, even when the zone detection failed. For that to work,
I had to change some node pointers to node identifiers in the zone structs, so
that it is safe to access them even if the nodes have been removed.

This feature greatly increase depth buffer precision.
This is very noticeable in large view distance scenes.
This is enabled by default on GPUs that supports it (most of the hardware we
support already supports this). This makes rendering different on the GPUs
that do not support that feature (`glClipControl`).
While this give much better depth precision as before, we also have a lot of
imprecision caused by our vertex transformations. This can be improved in
another task.

Previously, internal links of node are only shown when the link is muted AND
when the corresponding output is linked to something else. I can't think of any
reason for why it's important whether the output is linked or not. It seems
showing the internal link is always useful.
This patch makes it so that all internal links are always shown when a node is
muted, regardless of whether the corresponding output socket is linked or not.

Previously, when adding a group node it was always called `Group`. This is not
particularly useful. Also it's inconsistent with many other places like adding
modifiers where the name of the modifier depends on what modifier is added.
Now, newly added group node will have the same name as the group that it calls.
Node names still have to be unique though, so e.g. `.001` is still added.
