d6fef73ef1 WM: Remove ASCII members from wmEvent & GHOST_TEventKeyData
The `ascii` member was only kept for historic reason as some platforms
didn't support utf8 when it was first introduced.

Remove the `ascii` struct members since many checks used this as a
fall-back for utf8_buf not being set which isn't needed.
There are a few cases where it's convenient to access the ASCII value
of an event (or nil) so a function has been added to do that.

*Details*

- WM_event_utf8_to_ascii() has been added for the few cases an events
  ASCII value needs to be accessed, this just avoids having to do
  multi-byte character checks in-line.

- RNA Event.ascii remains, using utf8_buf[0] for single byte characters.

- GHOST_TEventKeyData.ascii has been removed.

- To avoid regressions non-ASCII Latin1 characters from GHOST are
  converted into multi-byte UTF8, when building X11 without
  XInput & X_HAVE_UTF8_STRING it seems like could still occur.

c355be6fae UI: Add AbstractView base class for views, unify reconstruction in there
No user visible changes expected.

There's plenty of duplicated code in the grid and the tree view, and I expect
this to become more. This starts the process of unifying these parts, which
should also make it easier to add new views. Complexity in the view classes is
reduced, and some type shenanigans for C compatibility and general view
management can be removed, since there is now a common base type.

For the start this ports some of the view reconstruction, where the view and
its items are compared to the version of itself in the previous redraw, so that
state (highlighted, active, renaming, collapsed, ...) can be preserved.
Notifier listening is also ported.

65166e145b Cleanup: Remove scene frame macros (CFRA et al.)
Removes the following macros for scene/render frame values:
- `CFRA`
- `SUBFRA`
- `SFRA`
- `EFRA`

These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):
```
CFRA = some_frame_nbr;
```

23d2e77a54 UI: Add initial "grid view"
Part of T98560.
See https://wiki.blender.org/wiki/Source/Interface/Views

Adds all the basic functionality needed for grid views. They display
items in a grid of rows and columns, typically with a preview image and
a label underneath. Think of the main region in the Asset Browser.

Current features:
- Active item
- Notifier listening (also added this to the tree view)
- Performance: Skip adding buttons that are not scrolled into view
  (solves performance problems for big asset libraries, for example).
- Custom item size
- Preview items (items that draw a preview with a label underneath)
- Margins between items scale so the entire region width is filled with
  column, rather than leaving a big empty block at the right if there's
  not enough space for another column (like the File and current Asset
Browser does it).
- "Data-View Item" theme colors. Not shown in the UI yet.

No user visible changes expected since the grid views aren't used for
anything yet.

This was developed as part of a rewrite of the Asset Browser UI
(`asset-browser-grid-view` branch), see T95653. There's no reason to
keep this part in a branch, continuing development in master makes
things easier.

Grid and tree views have a lot of very similar code, so I'm planning to
unify them to a degree. I kept things separate for the start to first
find out how much and what exactly makes sense to override.

1f85877263 Fix T98461: Crash running screenshot from the command-line
When launching Blender with a script creating a screenshot, the Outliner
tree wasn't initialized and built properly. That is because at this
stage, all visible regions were only tagged for a non-rebuild redraw,
not a full redraw. So ensure all regions are tagged for a full redraw
immediately after file reading. Usually the full redraw would be caused
by a file-read notifier, but the Python expression/script is executed
before notifiers are handled.

Note that even before this was crashing, the Outliner would be empty in
the created screenshot.

Additionally adds an assert to the Outliner to note assumptions
explicitly, rather than crashing later.

I added a completely new mode (`OB_MODE_SCULPT_CURVES`), because
`OB_MODE_SCULPT` seems to be rather specific to meshes, and reusing

This commit adds a new operator that allows updating the preview

Note, the operator can also be used for other asset types, not just

a21bca0e20 Performance: Remap multiple items in UI
During sprite fright loading of complex scenes would spend a long time in remapping ID's
The remapping process is done on a per ID instance that resulted in a very time consuming
process that goes over every possible ID reference to find out if it needs to be updated.

If there are N of references to ID blocks and there are M ID blocks that needed to be remapped
it would take N*M checks. These checks are scattered around the place and memory.
Each reference would only be updated at most once, but most of the time no update is needed at all.

Idea: By grouping the changes together will reduce the number of checks resulting in improved performance.
This would only require N checks. Additional benefits is improved data locality as data is only loaded once
in the L2 cache.

It has be implemented for the resyncing process and UI editors.
On an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz 16Gig the resyncing process went
from 170 seconds to 145 seconds (during hotspot recording).

After this patch has been applied we could add similar approach
to references (references between data blocks) and functionality (tagged deletion).
In my understanding this could reduce the resyncing process to less than a second.

0f89bcdbeb Fix depsgraphs sharing IDs via evaluated edit mesh
The evaluated mesh is a result of evaluated modifiers, and referencing
other evaluated IDs such as materials.
It can not be stored in the EditMesh structure which is intended to be
re-used by many areas. Such sharing was causing ownership errors causing
bugs like

  T93855: Cycles crash with edit mode and simultaneous viewport and final render

The proposed solution is to store the evaluated edit mesh and its cage in
the object's runtime field. The motivation goes as following:

- It allows to avoid ownership problems like the ones in the linked report.
- Object level is chosen over mesh level is because the evaluated mesh
  is affected by modifiers, which are on the object level.

This patch allows to have modifier stack of an object which shares mesh with
an object which is in edit mode to be properly taken into account (before
the change the modifier stack from the active object will be used for all
objects which share the mesh).

There is a change in the way how copy-on-write is handled in the edit mode to
allow proper state update when changing active scene (or having two windows
with different scenes). Previously, the copt-on-write would have been ignored
by skipping tagging CoW component. Now it is ignored from within the CoW
operation callback. This allows to update edit pointers for objects which are
not from the current depsgraph and where the edit_mesh was never assigned in
the case when the depsgraph was evaluated prior the active depsgraph.

There is no user level changes changes expected with the CoW handling changes:
should not affect on neither performance, nor memory consumption.

Tested scenarios:

- Various modifiers configurations of objects sharing mesh and be part of the
  same scene.

- Steps from the reports: T93855, T82952, T77359

This also fixes T76609, T72733 and perhaps other reports.

cfa53e0fbe Refactor: Move normals out of MVert, lazy calculation
As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.

The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.

The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).

**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code

In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).

Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.

**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
 - Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
   showing that accessing just `MVert` is now more efficient.
 - Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
   change that at least shows there is no regression.
 - Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
   but observable speedup.
 - Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
   shows that using normals in geometry nodes is faster.
 - Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
   shows that calculating normals is slightly faster now.
 - File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
   Normals are not saved in files, which can help with large meshes.

As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.

**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
 - The subdivision surface modifier is not responsible for calculating
   normals anymore. In master, the modifier creates different normals
   than the result of the `Mesh` normal calculation, so this is a bug
   fix.
 - There are small differences in the results of some modifiers that
   use normals because they are not converted to and from `short`
   anymore.

**Future improvements**
 - Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
   already retrieves normals if they are needed anyway.
 - Copy normals as part of a better CoW system for attributes.
 - Make more areas use lazy instead of eager normal calculation.
 - Remove `BKE_mesh_normals_tag_dirty` in more places since that is
   now the default state of a new mesh.
 - Possibly apply a similar change to derived face corner normals.

fb6bd88644 Revert "BLI: Refactor vector types & functions to use templates"
Includes unwanted changes

This reverts commit 46e049d0ce.

46e049d0ce BLI: Refactor vector types & functions to use templates
This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.

In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.

####Motivations:
 - We are aiming to share UBO and SSBO structures between GLSL and C++.
 This means we will use many of the existing vector types and others
 we currently don't have (uintX, intX). All these variations were
 asking for many more code duplication.
 - Deduplicate existing code which is duplicated for each vector size.
 - We also want to share small functions. Which means that vector
 functions should be static and not in the class namespace.
 - Reduce friction to use these types in new projects due to their
 incompleteness.
 - The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
 bit of a let down. Most clases are incomplete, out of sync with each
 others with different codestyles, and some functions that should be
 static are not (i.e: `float3::reflect()`).

####Upsides:
 - Still support `.x, .y, .z, .w` for readability.
 - Compact, readable and easilly extendable.
 - All of the vector functions are available for all the vectors types
 and can be restricted to certain types. Also template specialization
 let us define exception for special class (like mpq).
 - With optimization ON, the compiler unroll the loops and performance
 is the same.

####Downsides:
 - Might impact debugability. Though I would arge that the bugs are
 rarelly caused by the vector class itself (since the operations are
 quite trivial) but by the type conversions.
 - Might impact compile time. I did not saw a significant impact since
 the usage is not really widespread.
 - Functions needs to be rewritten to support arbitrary vector length.
 For instance, one can't call `len_squared_v3v3` in
 `math::length_squared()` and call it a day.
 - Type cast does not work with the template version of the `math::`
 vector functions. Meaning you need to manually cast `float *` and
 `(float *)[3]` to `float3` for the function calls.
 i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
 - Some parts might loose in readability:
 `float3::dot(v1.normalized(), v2.normalized())`
 becoming
 `math::dot(math::normalize(v1), math::normalize(v2))`
 But I propose, when appropriate, to use
 `using namespace blender::math;` on function local or file scope to
 increase readability.
 `dot(normalize(v1), normalize(v2))`

####Consideration:
 - Include back `.length()` method. It is quite handy and is more C++
 oriented.
 - I considered the GLM library as a candidate for replacement. It felt
 like too much for what we need and would be difficult to extend / modify
 to our needs.
 - I used Macros to reduce code in operators declaration and potential
 copy paste bugs. This could reduce debugability and could be reverted.
 - This touches `delaunay_2d.cc` and the intersection code. I would like
 to know @howardt opinion on the matter.
 - The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
 But according to @JacquesLucke it is not a real problem for now.

I would like to give a huge thanks to @JacquesLucke who helped during this
and pushed me to reduce the duplication further.

classes (inside the blender::math namespace) and are not vector size
dependent for the most part.

In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.

Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
  This means we will use many of the existing vector types and others we
  currently don't have (uintX, intX). All these variations were asking
  for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector functions
  should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
  incompleteness.
- The current state of the BLI_(float|double|mpq)(2|3|4).hh is a bit of a
  let down. Most clases are incomplete, out of sync with each others with
  different codestyles, and some functions that should be static are not
  (i.e: float3::reflect()).

Upsides:
- Still support .x, .y, .z, .w for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types and
  can be restricted to certain types. Also template specialization let us
  define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance is
  the same.

Downsides:
- Might impact debugability. Though I would arge that the bugs are rarelly
  caused by the vector class itself (since the operations are quite trivial)
  but by the type conversions.
- Might impact compile time. I did not saw a significant impact since the
  usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length. For
  instance, one can't call len_squared_v3v3 in math::length_squared() and
  call it a day.
- Type cast does not work with the template version of the math:: vector
  functions. Meaning you need to manually cast float * and (float *)[3] to
  float3 for the function calls.
  i.e: math::distance_squared(float3(nearest.co), positions[i]);
- Some parts might loose in readability:
  float3::dot(v1.normalized(), v2.normalized())
  becoming
  math::dot(math::normalize(v1), math::normalize(v2))
  But I propose, when appropriate, to use
  using namespace blender::math; on function local or file scope to
  increase readability. dot(normalize(v1), normalize(v2))

Consideration:
- Include back .length() method. It is quite handy and is more C++
  oriented.
- I considered the GLM library as a candidate for replacement.
  It felt like too much for what we need and would be difficult to
  extend / modify to our needs.
- I used Macros to reduce code in operators declaration and potential
  copy paste bugs. This could reduce debugability and could be reverted.
- This touches delaunay_2d.cc and the intersection code. I would like to
  know @Howard Trickey (howardt) opinion on the matter.
- The noexcept on the copy constructor of mpq(2|3) is being removed.
  But according to @Jacques Lucke (JacquesLucke) it is not a real problem
  for now.

I would like to give a huge thanks to @Jacques Lucke (JacquesLucke) who
helped during this and pushed me to reduce the duplication further.

5de109cc2d Remove G.relbase_valid
In almost all cases there is no difference between `G.relbase_valid`
and checking `G.main->filepath` isn't an empty string.

In many places a non-empty string is already being used instead of
`G.relbase_valid`.

The only situation where this was needed was when saving from
`wm_file_write` where they temporarily became out of sync.
This has been replaced by adding a new member to `BlendFileWriteParams`
to account for saving an unsaved file for the first time.

3850fdd5b9 Assets: Sanitize threaded preview creation with undo
Basically, this fixes disappearing previews when editing asset metadata
or performing undo/redo actions.

The preview generation in a background job will eventually modify ID
data, but the undo push was done prior to that. So obviously, an undo
then would mean the preview is lost.

This patch makes it so undo/redo will regenerate the preview, if the preview
rendering was invoked but not finished in the undone/redone state.

The preview flag PRV_UNFINISHED wasn't entirely what we needed. So I had to
change it to a slightly different flag, with different semantics.
