Generally, one does not know if the sharing info is currently shared
and should therefore be const. Better keep it const almost all the
time and only remove the constness when absolutely necessary
and the code has checked that it is valid.
The main challenge is to avoid dangling pointers. Currently, the lifetime of socket
declarations is somewhat unbounded (at least we didn't restrict it explicitly yet).
Therefore, storing non-owning pointers in it tricky. For ID pointers one could
potentially use the foreach-id iterator to update pointers in declarations as well,
but that's a bit out of scope and might not be the right solution anyway, since it's
not obvious that all node declarations are reachable from IDs stored in `bmain`.
The solution now is to use a callback that retrieves the right ID pointer when it
is used. The important thing is that the callback does not capture any potentially
dangling pointer either.

It was broken in two ways:
- bpy_bmlayercollection_iter passed PY_SSIZE_T_MIN, while
PY_SSIZE_T_MAX was needed.
- bpy_bmlayercollection_subscript_slice() contained an
off-by-one error.

Completes the TODO in GHOST_SystemPathsCocoa::addToSystemRecentFiles
Also renames the filename parameter to the more appropriate filepath.
The recently opened/saved file will now also show up in:
- Blender Dock icon > Right click.
- Three finger swipe down in Open Blender i.e., App Expose
Based on a earlier contribution by @jenkm.

The crash can occur in the following situations:
- Attempt to open a corrupted EXR file
- Attempt to save an EXR file under a non-existing directory.
The root cause is not really clear: for some reason the OpenEXE API on
the Blender side can not catch OpenEXE exceptions by a constant
reference to a std::exception, although it can by a constant reference
to an Iex::BaseExc.
This does not seem to be an issue with the OpenEXR library itself as
the idiff tool from our SVN folder catches the exceptions correctly.
It is also not caused by the symbols_apple.map as erasing it does not
make the problem go away.
It could still be some compiler/visibility flag which we were unable
to nail down yet.
The proposed solution is to add catch-all cases, mimicking the OIIO
tools. This solves the problem with the downside is that there are
no friendly error messages in the terminal. Those messages could be
brought as part of the workaround by additionally catching the
Iex::BaseExc exception. But probably nobody relies on those error
prints anyway, so added complexity in the code is likely does not
worth it.

Animation: Adds a new "Parent Space" Orientation option for the Transformation Gizmo.
---
For child targets (objects, bones, etc) being able to transform in parent space is a desired feature (especially when it comes to rigging / animation).
For objects:
* with a parent, the gizmo orients to it's parents orientation
* without a parent, the gizmo orients to Global space
For Armatures:
* Child bone shows parent's space regardless if "Local Location" is set for parent bone
* For root bone **without** "Local Location" set, use the armature objects space.
* For root bone **with** "Local Location" set, use local bone space.
---
No new transformation orientation code needs to be written, we can achieve the desired results be using the existing `transform_orientations_create_from_axis`, `ED_getTransformOrientationMatrix`, and `unit_m3` methods. To do this, we check to see if the bone has a parent, if so, we use the bones pose matrix (`pose_mat`). This is done similarly for objects using the parent's object matrix (`object_to_world`).

When a parent item was renamed, the `TreeView` was doing everything as
expected, however `AssetCatalogService::update_catalog_path` is supposed
to also update the catalog paths of all sub-catalogs [which it does --
but it does not tag sub-catalogs as having unsaved changes, resulting in
wrong saving of catalogs afterwards, meaning the parent item was saved
with the old name and a new item with the new name was created].
Now also tag sub-catalogs for having unsaved changes.
This should also go into 3.3 LTS

The selection (box select, click select...) had an offset when selecting keys in the timeline.
That was because the function to get the NLA mapping ignored the timeline.

Currently when a baked curve is in the Graph Editor and normalization is enabled, it doesn't work.
It even throws a warning.
This patch adds the missing logic to normalize baked FCurves within a preview range.

Shader source requires explicit conversions and shader address
space qualifers in certain places in order to compile for Metal.
We also require constructors for a number of default struct types.

This patch adds several tools and options to the weight paint mode of Grease Pencil.
* Blur tool: smooths out vertex weights, by calculating a gaussian blur of adjacent vertices.
* Average tool: painting the average weight from all weights under the brush.
* Smear tool: smudges weights by grabbing the weights under the brush and 'dragging' them.
* With the + and - icons in the toolbar, the user can easily switch between adding and subtracting weight while drawing weights.
* With shortcut `D` you can toggle between these two.
* The auto-normalize options ensures that all bone-deforming vertex groups add up to 1.0 while weight painting.
* With `Ctrl-F` a radial control for weight is invoked (in addition to the radial controls for brush size and strength).
* With `Ctrl-RMB` the user can sample the weight. This sets the brush Weight from the weight under the cursor.
* When painting weights in vertex groups for bones, the user can quickly switch to another vertex group by clicking on a bone with `Ctrl-LMB`.
For this to work, follow these steps:
* Select the armature and switch to Pose Mode.
* Select your Grease Pencil object and switch immediately to Weight Paint Mode.
* Select a bone in the armature with `Ctrl-LMB`. The corresponding vertex group is automatically activated.

This patch implements the ID Mask node for the realtime compositor.
The node can be implemented as a GPU shader operation when the
anti-aliasing option is disabled, which is something we should do when
the evaluator allows nodes be executed as both standard and GPU shader
operations.

The comment didn't really make sense, since the removed code did the
same thing as the CustomData function anyway, and that's already done
in `mesh_init_data`.
Some callers that access the extension operated on the end of the path
even when there was no extension. Using this avoids having to assign
the end of the string using a separate check.
The file extension was copied into a buffer without checking it's size.
While large extensions aren't typical, some callers used small fixed
size buffers so an unusually named file could crash.
Runtime this information is stored in the active_color_attribute and
default_color_attribute strings on the mesh, however when saving it
is still saved in the old format with flags on the CustomData layers.
When converting from the strings to the layers not all flags were
properly cleared from the CustomData layers, leading to multiple
layers having the CD_FLAG_COLOR_ACTIVE/RENDER flag.
Implicit sharing means attribute ownership is shared between geometry
data-blocks, and the sharing happens automatically. So it's unnecessary
to choose whether to enable it when copying a mesh.
The typical order is vertex, edge, face(polygon), corner(loop), but in
these three functions polys and loops were reversed. Also use more
typical "num" variable names rather than "len"
Create a "nomain" mesh when converting intermediate representations
to a Mesh, meaning those areas don't have to know about data-block
names or the main database, and also that the boilerplate of adding
attributes individually can be avoided. The attribute arrays aren't
copied here, so the performance should be unaffected.
The nodes for inverting a color are named simply Invert, which begs the question: invert what?
This patch changes the naming for the node in Shading, Texture and Compositing nodes to *Invert Color*
This matches the naming of other color dedicated nodes like Separate Color or Combine Color
