Pass the new selection mode instead of setting the value in the
BMEditMesh, then calling set.
This makes it possible to compare with the current selection mode
(needed for UV sync select #131642).
This merges the public `uiItemS` and `uiItemS_ex` functions into an
object oriented API (`uiLayout::separator`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code
(or vice-versa), making it almost seamless.

There are many RNA properties on the Mesh ID that were animatable, but
likely shouldn't be. For example:
- The vertex indices of edges and faces.
- The X/Y/Z mirroring toggles (effectively tool settings).
This PR marks these properties as non-animatable. The downside of doing
this is that it reduces opportunities for pranks, such as preventing
your coworkers from being able to toggle X-mirror. But that seems like
an acceptable price to pay for keeping this from happening accidentally,
and in some cases perhaps indirectly causing more serious issues.
Note that there are many, many more erroneously animatable properties
throughout Blender. This PR narrowly addresses just those that are part
of the Mesh ID type.

Instead of calling all of these functions from `RNA_def_nodetree`, call them
from their respective node callbacks. This didn't work a few months ago, because
these callbacks did not have the `brna` argument back then.

Prior to this commit, the Dyntopo panel was hardcoded to display as
faded if the current brush was the mask brush. This conflicts with the
common set of brushes which we do not support dyntopo for, which
includes many other brushes.
This commit changes the check to better indicate that certain brushes do
not support dyntopo. The scene-level settings can still be changed & the
detail flood fill operator remains functional even if the a different
brush is selected.
Additionally, the panel is no longer greyed out if the "Manual" option is
active.

These are generic properties of grids (not stored in voxels) which are

This patch removes the Gamma option from the Defocus and Blur nodes. The
reasoning is as follows.
- The option was originally added when the compositor wasn't working on
a strictly linear workflow. So this is rarely needed now.
- It is easy to insert a Gamma node around Blur nodes to perform any
gamma correction if really needed.
- Since we are moving options to inputs, it doesn't seem worth it to
provide this option as an input in the process.

There are two implementations:
- "Link to Viewer Node"
-- when clicking on a socket directly, link from that socket [done by
first selecting and then taking that selection state into account]
-- otherwise cycles through available sockets
- "Connect to Output" [python operator, made core from Node Wrangler]
-- does not take socket selection into account
-- only cycles through available sockets
So goal is to replicate behavior of "Link to Viewer Node" in "Connect to
Output" in terms of "which socket to link from"
This is done by
- exposing a sockets select state to python
- tweaking the call to bpy.ops.node.select so it does socket selection
as well
- take that selection into account

As described in #122398, implement read and write support for a new
attribute storage system. Currently this is only implemented to support
forward compatibility; the format used at runtime isn't changed at all.
That can be done one step at a time during the 4.5 and 5.0 development
cycles. A new experimental option for testing tells Blender to always
save with the new format.
The main benefit of the new structure is that it matches the attribute
system design, it allows for future attribute storage optimization, and
each attribute is an allocated struct, which will give pointer stability
for the Python API.
The next step is to connect the attribute API and the RNA API to
AttributeStorage for the simplest geometry type, point clouds.

Briefly about this change:
- OpenColorIO C-API is removed.
- The information about color spaces in ImBuf module is removed.
It was stored in global ListBase in colormanagement.cc.
- Both OpenColorIO and fallback implementation supports GPU drawing.
- Fallback implementation supports white point, RGB curves, etc.
- Removed check for support of GPU drawing in IMB.
Historically it was implemented in a separate library with C-API, this
is because way back C++ code needed to stay in intern. This causes all
sort of overheads, and even calls that are strictly considered bad
level.
This change moves OpenColorIO integration into a module within imbuf,
next to movie, and next to IMB_colormanagement which is the main user
of it. This allows to avoid copy of color spaces, displays, views etc
in the ImBuf: they were used to help quickly querying information to
be shown on the interface. With this change it can be stored in the
same data structures as what is used by the OpenColorIO integration.
While it might not be fully avoiding duplication it is now less, and
there is no need in the user code to maintain the copies.
In a lot of cases this change also avoids allocations done per access
to the OpenColorIO. For example, it is not needed anymore to allocate
image descriptor in a heap.
The bigger user-visible change is that the fallback implementation now
supports GLSL drawing, with the whole list of supported features, such
as curve mapping and white point. This should help simplifying code
which relies on color space conversion on GPU: there is no need to
figure out fallback solution in such cases. The only case when drawing
will not work is when there is some actual bug, or driver issue, and
shader has failed to compile.
The change avoids having an opaque type for color space, and instead
uses forward declaration. It is a bit verbose on declaration, but helps
avoiding unsafe type-casts. There are ways to solve this in the future,
like having a header for forward declaration, or to flatten the name
space a bit.
There should be no user-level changes under normal operation.
When building without OpenColorIO or the configuration has a typo or
is missing a fuller set of color management tools is applies (such as the
white point correction).

This patch removes the Max Blur option from the Bokeh Blur node. The
reasoning is as follows.
- The option was unused in case of non-variable sized blur, which was
the default, so the option did nothing for the default case of the
node.
- The option was originally introduced to define the search window of
variable size blur. This is no longer the case, since we compute the
search window dynamically from the input using parallel reduction,
which is now very fast. So currently, it only works as an upper limit.
- The node options will be exposed as inputs, so the user will see two
inputs that control the radius, which can be confusing for users that
are not experienced.
- The plan is to make the node take absolute pixel sizes in the future,
instead of the arbitrary relative size now in place, which would make
it very easy for the user to impose such limits manually.
It is difficult to version this change, since the size is relative to
the image size, while max blur is in pixels. But we assume the user
chose a sufficiently large max blur for the node to be useful, so the
composite should not be expected to be drastically different.

This adds basic templating support to render output paths. By putting
"{variable_name}" in the path string, it will be replaced by the named
variable's value when generating the actual output path. This is similar
to how "//" is already substituted with the path to the blend file's
current directory.
This templating system is implemented for both the primary render output
path as well as the File Output node in the compositing nodes. Support
for using templates in other places can be implemented in future PRs.
In addition to the "{variable_name}" syntax, some additional syntax is
also supported:
- Since "{" and "}" now have special meaning, "{{" and "}}" are now
escape sequences for literal "{" and "}".
- "{variable_name:format_specifier}", where "format_specifier" is a
special syntax using "#", which allows the user to specify how numeric
variables should be formatted:
- "{variable_name:###}" will format the number as an integer with at
least 3 characters (padding with zeros as needed).
- "{variable_name:.##}" will format the number as a float with
precisely 2 fractional digits.
- "{variable_name:###.##}" will format the number as a float with at
least 3 characters for the integer part and precisely 2 for the
fractional part.
For the primary render output path: if there is a template syntax error,
a variable doesn't exist, or a format specifier isn't valid (e.g. trying
to format a string with "##"), the render that needs to write to the
output path fails with a descriptive error message.
For both the primary and File Output node paths: if there are template
syntax errors the field is highlighted in red in the UI, and a tooltip
describes the offending syntax errors. Note that these do *not* yet
reflect errors due to missing variables. That will be for a follow-up
PR.
In addition to the general system, this PR also implements a limited set
of variables for use in templates, but more can be implemented in future
PRs. The variables added in this PR are:
- `blend_name`: the name of the current blend file without the file
extension.
- `fps`: the frames per second of the current scene.
- `resolution_x` and `resolution_y`: the render output resolution.

Previously, menu sockets were always drawn as dropdown. This patch adds the
ability to draw them expanded instead.
As before, in the node editor, only the expanded menu is drawn, without the
label. There is simply not enough space for both. However, in the modifier and
operator settings the label is drawn currently. We'll probably need to add a
separate `Hide Label` option (similar to `Hide Value`) for group inputs that
support it. That would also help a lot with e.g. object sockets.

When a new node tree becomes active based on the context, the node editor was
not centered on the new tree. This can easily lead to the situation where there
is no node visible, and the user first has to search for the nodes.
The reason for this is unexpectedly special:
* `snode_set_context` calls `ED_node_tree_start` which adds the `NC_SCENE |
ND_NODES` notifier.
* Typically, this would update the `View2D` of the region in
`node_area_listener`.
* However, `snode_set_context` is called from
`wm_event_do_refresh_wm_and_depsgraph` which happens after(!) the listeners
run. Therefore, the node editor is redrawn before the listener is handled.
* During redraw, the stored view center is overridden. When it is later used in
the listener, the value is lost already.
This patch solves this by updating the view center eagerly when opening changing
what node tree is visible, instead of trying to it lazily where the required
information might be lost already.

This patch removes the Premultiplied option from the Alpha Over node.
The reasoning is as follows:
- The option mixed between alpha being straight and premultiplied, a
state which doesn't happen in practice.
- The option conflicts with the Convert Premultiplied option, if it is
not zero, then Convert Premultiplied does nothing.
- The option is implemented in a lossy way. It premultiplies the alpha
assuming it is straight, then converts the result to straight again,
then mixed between both results. This is as opposed to mixing the
original straight input with the premultiplied input. The successive
alpha conversion causes data loss in transparent regions.

This adds inital Grease Pencil support for node tools.
Node tools work in `Object Mode`, `Edit Mode`,`Sculpt Mode`,
and `Draw Mode`.
While Grease Pencil has many editing tools, including editing
multiple frames at the same time, for now, node tools only
allow editing the current frame.
Currently, the idea is that node tools can do arbitrary changes
to the drawings, but cannot do changes to the existing layer tree, e.g.
changing the order of layers, removing a layer or groups, etc.
All the node tool specific nodes like `Selection` and `Set Selection`
are adapted to work with Grease Pencil. In `Draw Mode`, we currently
interpret everything as selected.
The `Active Element` node has a `Layer` mode that provides the
index of the active layer (if there is one).
When `Auto-Key` is used, a new keyframe is created on the
current frame.
Locked/invisible layers cannot be edited with node tools.

This patch removes the Convert Premultiplied option from the Brightness
and Contrast node. The reasoning is that it is the only node that has
the option to operate on straight alpha, while not being particularly
different. Adding alpha conversion nodes around it is also very easy.
Furthermore, alpha conversion is a lossy operation, so the option looses
data in emissive pixels, and since it is enabled by default, users not
familiar with the exact mechanism of the option wouldn't know how to fix
this.

This patch removes the Use Alpha option from Composite and Viewer nodes.
The reasoning for the removal is as follows:
- It has an unintuitive complicated design at the moment.
- If the Alpha Input is unlinked, the output alpha is not adjusted
even if Use Alpha is enabled, leaving users wondering why their
adjustments have no effect.
- Disabled Use Alpha means output an opaque image, that is, it
actually means Ignore Alpha. Which is confusing because users might
think that it controls alpha adjustments based on input.
- It always does alpha replacement without premultiplication, which is
not clear to the user and is not what the user wants in most cases.
- Adding a Set Alpha node before the output is pretty easy and clear, so
the option seems redundant considering the above.

This patch removes the Variable Size blur option from the Blur and Bokeh
Blur nodes. So now, whatever the user connects to the size input will be
used, be it variable or constant.
The option previously could be used to force the node to ignore variable
size inputs and assume a size of 1, so it was useless.
Versioning would be difficult, as we don't know if incoming links to the
size input is variable or single. So this is a breaking change. But I
can't think of a real reason why the user might use this option, so this
seems safe from a practical point of view.

This patch turns the options of the Bilateral Blur node into inputs.
In the process, the Sigma Space and Iterations were joined into a single
Size input, previously they were just added together then ceiled to get
the blur size. Furthermore, Sigma Color was renamed to threshold and now
represents the average color difference, not the sum, so it was
previously multiplied by 3.
Versioning and RNA compatibility is not perfect due to joining the two
size options.

Fixes for #137856 & #137507 were workarounds to ignore the

were error prone - especially #137856 as it relied on the surrounding

Instead of adding logic to ignore the flag for this specific case,
add a property to the CollectionExport which can have it's flags
and use this instead of the operators "filepath" property.
Internally this wraps the same IDProperty data used by the operator.
