This introduces a new `UI_MT_button_context_menu` class which is
registered at startup. Addons can append/prepend draw functions to this
class, in order to add their custom context menu entries.
The new class replaces the old `WM_MT_button_context` class, thus
requiring a small change in addons using this feature. This is done
because addons were previously required to register the class
themselves, which caused addons to override each other's context menu
entries.
Now the class registration is handled by Blender, and addons need only
append their draw functions. The new class name ensures that addons
using the old method don't override menu entries made using the new
class.
Menu entries added with the legacy `WM_MT_button_context` class are
still drawn for backwards compatibility, but this class must not be used
going forward, as any addon using it still runs the risk of having its
menu entries overridden, and support for the legacy class is subject to
removal in a future version.

At least Depsgraph evaluation and liboverride diffing do process IDs in
parallel, so python code in py-defined properties should not access any
data outside of their owner ID.
Ref. T100203.
Adds an example python script to the documentation for the 3D_IMAGE shader.
The **use-case** is to draw textures with 3D vertex positions, in XR views as well as non-XR views (in a simpler manner).
**Testing**: I've tested that this compiles and works on my Macbook (with the example python script included in this change). I don't have access to a Windows or Linux machine right now, but this change doesn't look platform-specific and no new glsl shaders have been added or edited by this change. I'll try to get access to a Windows machine, but if someone does have one, I'd be really grateful if they could try this change. Thanks!
**Problem addressed**: The existing 2D_IMAGE shader (exposed in the python API) gets near-clipped when drawn in the
XR view, regardless of the near-clip settings. Additionally, the 2D_IMAGE shader only accepts 2D
positions for the image vertices, which means drawing textures in 3D requires providing
2D coordinates and then pushing a transform-rotate-scale matrix to the GPU, even for
non-XR (i.e. WINDOW) views. The 3D_IMAGE shader is simpler: it accepts 3D vertex positions, and doesn't require
any additional work by the scripter.
**Workaround**: The current workaround is to use custom shaders in the python script.
**Non-intrusive change**: No new glsl shaders were added. This change just bundles two existing shaders: the vertex shader used
by the 3D_IMAGE_MODULATE_ALPHA shader, and the fragment shader used by the 2D_IMAGE shader.

Support a way to temporarily override the context from Python.
- Added method `Context.temp_override` context manager.
- Special support for windowing variables "window", "area" and "region",
other context members such as "active_object".
- Nesting context overrides is supported.
- Previous windowing members are restored when the context exists unless
they have been removed.
- Overriding context members by passing a dictionary into operators in
`bpy.ops` has been deprecated and warns when used.
This allows the window in a newly loaded file to be used, see: T92464

The use case for this method is quite obscure and difficult to
understand without an example. Despite how big looks, this is
actually the simplest example that makes sense.
After new AUD API changes from 2.8x what "buffer" function used to do
has now become "cache" function (it caches a sound into RAM). Therefore,
the basic aud example should call this new "cache" function instead of
"buffer" function.
Thanks to Michael-Z-Freeman for pointing out.
Combining location, rotation and scale channels into a matrix is
a standard task, so while it is easily accomplished by constructing
and multiplying 3 matrices, having a standard utility allows for
more clear code.
The new constructor builds a 4x4 matrix from separate location,
rotation and scale values. Rotation can be represented as a 3x3
Matrix, Quaternion or Euler value, while the other two inputs
are vectors. Unneeded inputs can be replaced with None.

This patch adds a to_curve method to the Object ID. This method is
analogous to the to_mesh method. The method can operate on curve and
text objects. For text objects, the text is converted into a 3D Curve ID
and that curve is returned. For curve objects, if apply_modifiers is
true, the spline deform modifiers will be applied and a Curve ID with
the result will be returned, otherwise a copy of the curve will be
returned.
The goal of this addition is to allow the developer to access the splines
of text objects and to get the result of modifier applications which was
otherwise not possible.

Blender can crash while rendering, when scene data is changed from within
a `frame_change_pre` or `frame_change_post` callback function. This results
in bug reports like T60094, T67627, and T73530. Until this is properly
resolved, this limitation should be documented.
No functional changes.
`object` is the superclass of all objects. Old-style code could still be
using `class SomeClass(object)` and assigning something else to `object`
could have unexpected results.
This is now also documented in the
[Python style guide](https://wiki.blender.org/wiki/Style_Guide/Python)
on the wiki.
