fa007002b1 Refactor: Logging: Move G.quiet to CLOG, replace some printfs
* Replace G.quiet by CLG_quiet_set/get
* CLOG_INFO_NOCHECK prints are now suppressed when quiet, these were
  typically inside a if (!G.quiet) conditional already.
* Change some prints for blend files, color management and rendering to
  use CLOG, that were previously using if (!G.quiet) printf().

6f426f498a Refactor: Move pass name aliasing to context implementation
This patch moves the rules that alias Image to Combined for pass names
to the context implementations. This is because this only makes sense
for contexts that deal with passes, while it wouldn't make much sense
for other possible contexts like VSE modifiers.

649b89781e Cleanup: ensure UTF8 string copy for DNA & screen data
Use `BLI_strncpy_utf8` & `BLI_snprintf_utf8` for fixed size buffers in
DNA and screen data structures such as panels, menus & operators.

This could be considered a fix as copying a UTF8 string into a smaller
buffer without proper truncation can create an invalid UTF8 sequence.
However identifying which of these users are likely to run into would
be time consuming and not especially useful.

e34e6373b6 Compositor: Replace Composite node with Group Output node
This patch replaces the Composite node with the Group Output node as the
primary compositor output. The old node was removed and versioned. This
was done for consistency with Geometry Nodes and in preparation for more
generic use of the compositor in VSE modifiers, layered compositing, NPR
multi-stage compositing, and more.

The Group Output node relies on the node tree interface, so we now have
a default interface of a single input and a single output. For now, only
the first input is considered while the rest are ignored, just like the
Geometry Nodes design. Furthermore, the input is required to be of type
color. Warnings and errors are issues if any of those are not met, also
similar to Geometry Nodes.

This introduces a new limitation: Composite outputs can no longer exist
in node groups, since they obviously then act as their respective group
outputs.

A refactor for the compositor scheduler is needed to simplify the logic
after this change, but this will be done in a separate patch.

Mistake in b19696c0b8

Don't reference the data from the `Array` which will just be the inline
buffer if `require_tangent` is false (for displacement baking).

I still observe a crash when multires baking, but that's deep in Cycles

b19696c0b8 Mesh: Simplify tangents calculation
- Tangent calculation functions no longer use the CustomData struct as
  an input and output.
- The "orco" and UV map calculations are exposed as separate API
  functions to avoid a confusing internal choice between the two
- Redundancy in the API is removed, function names are clarified
- Code is moved to C++ namespace
- The "orco" case is clarified in the mesh draw tangent VBO extraction
- CD_TANGENT layers are not stored in CustomData anymore, so some of
  that infrastructure is removed.
- Broken logic for caching tangents in CustomData is removed. That
  hasn't worked for many years, if it every worked. We could investigate
  adding caching again later if that's helpful.

Overall the change is motivated by the need to move away from CustomData
for #122398. But the changes should be a general improvement that makes
the code easier to understand either way.

Testing for this PR included using the default render UV in materials,
referencing specific UV tangents by name, using the spherical position-
based tangents in a material, and baking textures (multires and normal
baking).

e2b898fea7 Fix #141132: Crash on background GP render
The crash seems to come from libepoxy GL functions pointing to null.
It seems that libepoxy "Automatically initializes as new GL functions are used."
and that to call a function without a GL context bound, the function
must have been called before with a bound context.

This just modifies the scope of the context binding from
DRW_module_exit to  RE_engines_exit, which seems the safest solution
for 4.5.

56d8c11304 Core: Add more variables for path templates
This PR adds several more built-in variables for path templates:

- `scene_name`: name of the current scene.
- `camera_name`: name of the current camera.
- `node_name`: only for paths owned by a node; the name of the node.
- `blend_name_lib`: name of the blend file of the ID the path property
  is on, sans file extension.
- `blend_dir`: path up to (but not including) the currently open blend
  file.
- `blend_dir_lib`: path up to (but not including) the blend file of the
  ID the path property is on.

Additionally, adding support for `node_name` required re-thinking the
"path template type" system a bit:

Previously, the the `PropertyPathTemplateType` of a property completely
dictated what variables were made available to it. However, if we stuck
with that system then we would need to split
`PROP_VARIABLES_RENDER_OUTPUT` into two enum items: one for "normal"
render output paths like the one that lives on the `Scene`, and one for
"node" render output paths like the ones on the File Output node.

Instead of doing that, this PR makes `PropertyPathTemplateType` only
responsible for dictating the "purpose-specific" variables. In this
case, render-specific variables like fps, resolution, etc. Then the
availability of variables like `node_name` are instead based on what
owns the path (a node or not, in this case). There are also general
variables, like `blend_name`, that are now available to all path
templates.

fdaaea6328 Core: Increase MAX_ID_NAME length from 66 to 258 (Blender 5.0)
Change the maximum data-block name from 64 to 256 bytes by increasing MAX_ID_NAME value.

Also increase a few related non-ID data name max size, essentially the action slots identifiers, as these are the primary key used to match an Action's slot to an ID by name.

Other sub-data (bones, modifiers, etc.) lengths are not modified here, as these can be made actual dynamic strings in the future, while keeping (a reasonable level of) forward compatibility, during the course of Blender 5 release cycles.

Implements #137608.

33b712f909 Core: Always use current open file for blend_name variable
Previously `blend_name` was using the same path to get its file name
as `//` used. However, the choice of path for `//` seems to be
bespokely chosen at each call site.  There may be a logic to it, but
if so it's not immediately clear what it is.

This PR changes `blend_name` to instead always use the currently open
("global") file path, making it well-defined and predictable for
users.

This also prepares better for PR #139438 for 5.0, which adds
`blend_name_lib`, which always uses the blend file that the ID owning
the path is linked from. Over-all this should be much more predictable
and controllable for users.

bd61e69be5 Compositor: make compositor node trees reusable
This is part of the short term roadmap goal of simplifying the
compositor workflow
(see https://projects.blender.org/blender/blender/issues/134214).
The problem is that many users don't know how to get started with
compositing in Blender, even when they have used Blender for other
areas, e.g. modeling.

Note: although the solution makes compositor node trees reusable
accross blend files, this is a nice side effect and not the main goal
of the PR.

This PR implements a "New" button that creates a new compositing node
tree, and manages trees as IDs. This has following advantages:
- Consistent with other node editors and other parts of Blender,
therefore making it easier to getting started with compositing if users
are familiar with shading or geometry nodes
- Give users the ability to reuse the compositing node tree by linking
or appending it.

Note: The parameter "Use Nodes" is still present in this PR, but will
be removed (in a backward compatible way) in a follow up PR.

f685f23434 ImBuf: Remove pre-2.80 Texture mipmaps/filters
Removes various image filtering/mipmapping leftovers from
pre-2.80 days.

Code: removes all mipmap handling from ImBuf (which is about half of
ImBuf struct size), removes now unused "sample procedural texture
with mipmaps" code, now-unused FELINE filter, etc. The osatex
parameter to various CPU texture sampling functions is never
actually used, which means none of the mipmap code was ever executing.

User visible part: there were settings on the legacy Texture data
block (as used by Brushes etc.), under Sampling section: "MIP Map",
"Gaussian Filter", "Filter Type", "Eccentricity", "Minimum Size" --
they had no effect anywhere, so they are gone, and what remains is
only "Interpolation" and "Size".

RNA / Python API part: removes the ImageTexture RNA properties
corresponding to the above: filter_type, use_mipmap, use_mipmap_gauss,
filter_lightprobes, filter_eccentricity, use_filter_size_min.

5ff12bdc98 Core: Show all path template errors in the UI
The path templates feature implemented in #134860 highlights path
properties that have syntax errors in red and provides a list of those
errors in the path's tool tip. However, syntax errors are not the only
kind of error.

For example, if given the render output path `//render/{blend_nam}`,
with a typo in the variable `blend_name`, this error is not indicated
until actually trying to render. This is because the path is
*syntactically* correct, and the error is due to `blend_nam` not being
an available variable.

This PR resolves this: paths with path template support now indicate all
errors in the UI, not just syntax errors, with red highlights and a list
of errors in the tool tip.

The primary mechanisms for this are:
- A new function `BKE_build_template_variables_for_prop()`, which takes
an RNA pointer and produces an appropriate template variable map for the
given property, which can then be used to fully validate a path
property's value in the UI code.
- A new enum `PropertyPathTemplateType` has been added to `PropertyRNA`,
which determines what variables should be made available to a property
and how they should be build. This is used by
`BKE_build_template_variables_for_prop()`.

Additionally, the following changes have been made to help ensure that
`BKE_path_apply_template()` and `BKE_path_validate_template()` produce
identical errors:
- Both functions now call into a third static function `eval_template()`
  that does the actual work, optionally modifying the input path or not.
- Previously only `BKE_path_apply_template()` had unit tests, but now
  the unit tests have been reorganized to simultaneously test both
  `BKE_path_apply_template()` and `BKE_path_validate_template()`.

75f55a9e8e Fix #138493: Placeholders and Renders filenames dont match

Logic for touching placeholder files in `RE_RenderAnim` uses
`BKE_scene_multiview_filepath_get` (no matter if only a single view is
enabled), but logic in `BKE_image_render_write` falls back to using the
"regular" filepath (once gotten from `BKE_image_path_from_imformat`) if
there are less than two views.

That would also break the behavior of "Skip Overwrite".

Digging in git history is a bit hard, so not exactly sure why this was
added, but this PR changes behavior so that
`BKE_scene_multiview_filepath_get` is always used (even for a single
(non-empty) view. Done by implementing `RE_ResultIsMultiView`

e0beb7afe6 Templates for render output paths
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.

Like other runtime structs, it doesn't make sense to write this
data to files. And moving it out of DNA to an allocated C++ struct
means we can use other C++ features in it, like the new Mutex
type which I switched to in this commit.

b7a1325c3c BLI: use blender::Mutex by default which wraps tbb::mutex
This patch adds a new `BLI_mutex.hh` header which adds `blender::Mutex` as alias
for either `tbb::mutex` or `std::mutex` depending on whether TBB is enabled.

Description copied from the patch:
```
/**
 * blender::Mutex should be used as the default mutex in Blender. It implements a subset of the API
 * of std::mutex but has overall better guaranteed properties. It can be used with RAII helpers
 * like std::lock_guard. However, it is not compatible with e.g. std::condition_variable. So one
 * still has to use std::mutex for that case.
 *
 * The mutex provided by TBB has these properties:
 * - It's as fast as a spin-lock in the non-contended case, i.e. when no other thread is trying to
 *   lock the mutex at the same time.
 * - In the contended case, it spins a couple of times but then blocks to avoid draining system
 *   resources by spinning for a long time.
 * - It's only 1 byte large, compared to e.g. 40 bytes when using the std::mutex of GCC. This makes
 *   it more feasible to have many smaller mutexes which can improve scalability of algorithms
 *   compared to using fewer larger mutexes. Also it just reduces "memory slop" across Blender.
 * - It is *not* a fair mutex, i.e. it's not guaranteed that a thread will ever be able to lock the
 *   mutex when there are always more than one threads that try to lock it. In the majority of
 *   cases, using a fair mutex just causes extra overhead without any benefit. std::mutex is not
 *   guaranteed to be fair either.

 ```

The performance benchmark suggests that the impact is negilible in almost
all cases. The only benchmarks that show interesting behavior are the once
testing foreach zones in Geometry Nodes. These tests are explicitly testing
overhead, which I still have to reduce over time. So it's not unexpected that
changing the mutex has an impact there. What's interesting is that on macos the
performance improves a lot while on linux it gets worse. Since that overhead
should eventually be removed almost entirely, I don't really consider that
blocking.

2ab59859c9 Cleanup: VSE: Replace remaining seq and sequence references
Ref: #132179

Renames:
- `Editing.act_seq` -> `Editing.act_strip`
- `SequenceModifierData` -> `StripModifierData`
  - Its member `mask_sequence` is now `mask_strip`.
- `MetaStack.parseq` -> `MetaStack.parent_strip`
- Remaining function names/parameters that were not dealt with in #132748
- Various references to `seq` or `sequence` throughout code and docs when
  referring to a strip

Also moves `_get` to the end of the renamed function names where
applicable for standardization (unless "by" or "from" are used).

There should be no changes to current behavior.
