This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.

Spaghetti Transform code can use same code for different kind of data.
The 'stepped rotation' process is actually only useful/doable in a few
cases (when we do have some real place to store rotation value, and we
are using Eulers).
font_to_curve code was not handling properly the case where it has nop
object to check for mat indices validity. Check should just not happen
then, not reset mat indices of chars to default 0 value.
This fixes an incompatibility with Visual Studio 2019 introduced in
631d5026c7. It is likely caused by using
`# ifdef` inside the use of the `ELEM()` macro.
Use explicit boolean flag to indicate whether flush to original data
is needed or not. Makes it possible to avoid confusion on whether an

It was used to access evaluated object and pose and was done prior
to implementation of flushing values back to original data for an
active dependency graph.
Removing the argument allows to simplify API and solve issues with
accessing missing dependency graph on redo.
Simplify preferences by removing the ability to load them from
either the startup.blend or userpref.blend.
Also simplifies updating default preferences by moving
them to a struct definition.
This patch introduces the same presets that are used for proportional editing in the brush falloff menu. The user can select any of these presets or use the regular custom falloff curve. The presets are hardcoded formulas, so the falloff curve is not used when they are active.
This change improves the general feeling of the brushes and it is more convenient and simpler to use. The CUSTOM curve option should now be used in the case that an unusual deformation is needed, in other cases, the hardcoded curve presets should be the default.
The smooth curve presets is a must in the grab brush, as it fixes the deformation issue with the current custom curve setting. The user may try to adjust the deformation by tweaking the curve, but it is nearly impossible to replicate this desired behavior.
{F7636217}
Other brushes that are included in the sculpt branch also rely on this as they need specific hardcoded falloffs to produce the desired effect.

This function makes it possible to clear/remove/nuke all the geometry in
a mesh, allowing functions like `Mesh.from_python()` to construct a new
mesh in its place. Without this function, code like in T67627 have to
allocate a new Mesh datablock, fill that, and swap out the old Mesh for
the new one. This introduces issues when exporting, as the new mesh
could be seen by an exporter as unrelated to the old one.
Shape keys are not freed by this function. Freeing those would require
tagging the depsgraph for relations update, which is an expensive
operation. They should be removed explicitly if necessary.
Material slots are also not cleared by this function, in the same way
that they are not cleared when manually removing all geometry from a
mesh.
The `BKE_mesh_clear_geometry()` function is available in Python as
`mesh.clear_geometry()`.

Occasionally we get reports of people that build blender and end up
with either build errors or end up with builds that do not run on
other systems. The root cause is when you install vpckg and integrate
it into the build system it puts the search path for its includes and
libraries before anything else.
previously we told people to either uninstall vcpkg or remove the
conflicting packages, which was not great.
this change opts out of the use of vcpkg for blender only, so people
can keep using it for other work without issues.
The value of the step was calculated using a variable that was removed when the render frame change.
Now, the step is calculated using the modulus of the current frame and recalculate noise only if the remainder that results from performing integer division is equal to 0.
To calculate current frame, the first used frame is calculated to adjust real frame range.
This approach is more stable in viewport and render.
There was a fixed limit to the number of points available in a buffer stroke.
Now, the array is expanded as needed using a predefined number of points for each expansion, instead to add one by one. This is done to reduce the number of times the memory allocation is required.
As part of the fix, some variables have been renamed to reflect better their use.
When the mesh is using custom normals, those should always be exported,
regardless of the `ME_SMOOTH` flag on the invidivual polys.
Also replaced the loop normal writing with the same logic as we use for
reading (less pointer arithmetic, more normal counting).
Loop normals are called 'Face-varying normals' in Alembic. Before this
commit, the existence of such normals was used to enable smooth shading.
This is incorrect, as the normals could encode flat faces just as well.
This commit adds the loading of these normals as custom loop normals. It
then also enables Auto-Smoothing on the mesh (which is a bit of a
misnomer and indicates to Blender that the custom normals should be
used).
Fixes the glitching described in T65959.

When using the clone brush, the first time the brush worked, but the next time no. The reasons were two:
1) The strokes were copied to the active layer, but if there were more than one layer, the stroke must be copied to the original layer.
2) The materials were not assigned properly and the materials were set as the first slot in the list always.
Now, the original layer name is used to try to find the same layer in destination. If the layer is missing, the active layer is used.
For materials, the bug in the hash lookup is fixed and the material is assigned to the right slot.
The issue was that the redo panel area would call with region type HUD (not WINDOW).
Now we make sure that the redo panel always polls the operator in the original area type context.

While speedup is hard to detect (highly fluctuent), it seems to be
around 5% on average on my 8 threads machine...
It also remove usage of a 'global' thread lock, which is always good.
Note that I also tried to use proper foreach threaded iterator construct
(see D5372), but that proved to be relatively slower (presumably due to
the very high dissymmetry between tasks, usually during a paint stroke
only a few chunks will require most of the computing effort, overhead of
threaded foreach management is then noticeable).
This concludes (for now) the work on
T51133 Bad performance with texture painting depending on multi-thread settings.
Previously we were setting it to 1 (aka no 'chunking'), to follow
previous behavior. However, this is far from optimal, especially with
CPUs that can have tens of threads nowadays.
Now taking an heuristic approach (inspired from the one already existing
for `BLI_task_parallel_listbase()`, which tries to guesstimate best
chunk sizes based on several factors (amount of threads/parallel tasks,
total number of items, ...).
Think this is a reasonable base ground, more optimization here would of
course be possible.
Note that code that was already explicitely settings some value here
won't be affected at all by that change.
