The BMesh python API was fully broken by this commit.
While the fix seems to be reasonably simple, it is safer for now to revert
the faulty commit, as the breakage is fairly impactful for people using 4.5
and/or 5.0 daily builds.
This reverts commit bd3a66a416.
- Removes asserts where polygon shaders are used to draw lines and
points. This is incorrect and leads to asserts in Vulkan.
- Kept as close to the existing control flow. Didn't want to introduce
regressions as this PR lands in 4.5

Nodes code uses direct access to enum property values definition
(outside of the RNA API) to generate UI (translated) messages, this is
risky/messy since the i18n context potentailly defined for the actual
RNA property is not available in these cases.
A few reports used string formatting in a way which made translation
awkward, by splitting the message into several individually translated
submessages, instead of just one message with formatting markers.

Fix a crash in the inbetweener (and other similar tools) when bones have
custom properties, but no system properties. It just needed another
`nullptr` check.

When initially saving a file, we would now always create a catalog
definition file that would be writted to disk on file save. This
shouldn't be done if there are no new catalogs to write.
On the macOS deps builder, if certain libraries were installed
system-wide using Homebrew, they could be prioritized during the
linking of dependencies over our own versions, causing breakages
when running the built libraries on other systems.
For OpenColorIO, homebrew Imath could be linked if installed.
For TIFF (& libjpeg as a transitive dep), homebrew libdeflate
could be linked if installed.
This commit fixes both of these issues by directly specifying the
library path to prevent the linker from wrongly inferring it to a
system-wide path.
The `General` settings layout can be disabled by unchecking `use_custom_props`,
an since this button button is within this layout it can't be activated back.
NOTE: See that the button can be activated back if the checkbox is still
hovered after being unchecked, if the mouse moves out it can't be enabled back.

Auto normalization used to not work on assign/remove vertex group
operator, this was due to `BKE_object_defgroup_validmap_get` and
`vgroup_parray_alloc` did not handle grease pencil type objects. Now
added grease pencil cases in them and auto normalization works as
expected.

If view items button is active, call `ui_layout_list_set_labels_active` to
set the `SELECT` flag on label button. Due to this flag being set, text_sel theme
color is copied to `wcol.text` (see `UI_SELECT` condition in `widget_state()`).
This `wcol.text` is later used inside `widget_draw_text()` for text color.

Regression in [0] caused NDOF panning to be reversed
and zoom to be inverted in the 3D viewport.
- Use 2D viewport behavior for cameras & rotation locked views
since the navigation mode is not used in these cases.
- Restore the same zoom direction as 4.4x.

Adds a Point Instancing exporter based on the existing
USDPointInstancerReader. Covers both round-trip and Blender-native
workflows. Exports 'Instance on Points' setups as USDGeomPointInstancer,
supporting objects, collections, and nested prototypes.
A warning is shown during export if invalid prototype references are
detected. These would occur if an instancer attempts to instance itself.
This feature is currently gated behind an off-by-default export option
(`use_instancing`) as there are still a few cases which can yield
incorrect results.

The [Fix#125024: Bevel offset - eliminate divide by 0] (#126309)
in response to [Bevel Modifier creates unwanted geometries] (#125024)
created "divide by 0" situations when checking for clamp overlap geometry
in the bevel modifier. This PR eliminates this undefined behavior.
Original PR by Rob Blair. Modified by make format and added
a needed include.
When quiting Blender the timeline doesn't get updated and an assert is
triggered that the order isn't correct. The order isn't that important
anymore as the mechanism has been tested. The assert was useful during
initial development.
This PR removes the assert as it isn't valid in all cases.
This is due to missing `make_available` callback for Group ID socket.
Use it to change the mode of the merge layer node so that socket is
available in `connect_available_socket()`

This patch removes node init functions that currently exist only for
forward compatibility and moves the logic to the forward compatibility
section of node writing. This is to avoid allocating unused data
throughout the 5.x series.

While individual modes have UI tests related to undo, this new set of
tests in this new file is intended to be a set of very broad sanity
tests that catch the most egregious errors that cause crashing on start
up, whether due to python errors, UI rendering issues, or otherwise.
Running these tests takes approximately 4 seconds currently as it adds
and verifies the loading of each of the workspaces available "out of
the box" to a blender user.

It is possible for a mesh to change topology across frames but still be
detected as not needing a topology update.
Until we can make a finer-grained check against the before and after
topology, unconditionally ensure it's updated for now.
Adds a new test that checks a few frames of changing topology that is
similar, but not the same.

The curve interpolation operator write uninitialized data to vertex
attributes if there is more than one interpolated curve pair.
This is because _partial writes_ to `VArraySpan` wrappers only work
if the original VArray is already a span or if the wrapper span is
fully initialized with the original data beforehand.
In the case of the curve interpolation tool for Grease Pencil the
interpolation is invoked for each curve pair separately, creating a
new output attribute `VArraySpan` wrapper each time. This wrapper
is only filled for the curve pair in question and writes uninitialized
data to all the other curves' vertex weight attributes.
To prevent this from happening the simple solution is to use
`lookup_or_add_for_write_span` which initializes the entire span.
This causes quite a lot of unnecessary copying, but that is acceptable
for the Grease Pencil interpolation tool. The alternative is to change
the tool so that the destination GSpanAttributeWriter is only created
once, but that is a much bigger change.

This assert added by 321ec72c74 notes that changing the mesh
wrapper type from subdivision to normal mesh data just discards the
potentially-subdivided geometry and doesn't make sense, and possibly
breaks other assumptions.
This wrapper type change was done years ago by 0f89bcdbeb to
fix issues with shared object data during evaluation. It noted that
the mesh drawing data extraction didn't handle BMesh wrappers correctly
when the object isn't in edit mode, but that doesn't seem to be the
case after two trivial changes. The other bugs mentioned by that commit
are still solved after this change.

This PR moves back the wireframe slider option back to the
bones overlay popover. It is only showed in paint weight mode
and only active if in wireframe mode.
It was concluded that this feature should be revisited to maybe
cover all shading modes in the future. But for now it is safer
for 4.5 to limit it to the weightpaint mode.

This reverts commit 283ae193d9.
It causes issues because the deselection happens regardless of
properties actually getting keyed, meaning
i.e. setting interpolation modes was no longer possible
