When having a checkbox and a value both in one row together with an
animation decorator it is questionable whether the decorator should act
on animating the checkbox or the corresponding value. At the moment,
usage in modifiers does not seem to be very consistent:
Here the animation decorator works for animating the checkbox:
- `Build` (greasepencil) > `Factor` (this was reported and is changed in
this patch to act on the value instead of the checkbox)
- `DataTransfer` > `Topology Mapping` > `Max Distance` (this I guess
should also act on the value instead of the checkbox)
- `Edge Split` > `Edge Angle` (questionable)
- `Mirror` > `Merge` (questionable)
- `Screw` > `Merge` (questionable)
- `Wireframe` > `Crease Edges` (questionable)
Here the animation decorator works for animating the value:
- `VertexWeightEdit` > `Group Add/Remove Threshold`
- `Decimate` > `Symmetry`
So in this patch only the behavior in the greasepencil Build modifier UI
is changed, since I think it is quite obvious that one would more often
use the decorator for animating the factor value than for animating the
checkbox.

Materials used in grease pencil modifiers have the requirement that they
are already used on the object. In the UI dropdown, this restriction is
ensured by calling uiItemPointerR with appropriate searchptr and
searchpropname, so only giving the user the choice of materials already
used on the object.
From python though, it was still possible to assign materials outside of
this this restriction. This led to reports like T86981 [which have been
partially solved by clamping the material index in the modifier code to
be in the valid range].
Now make sure we dont assign "invalid" materials through RNA by
appropriate RNA pointer functions.
This also adds a proper warning (red, alert) in case of the LineArt
modifier if such a invalid material is still in the file [same as other
modifiers already do].

After some back and forth with the GP module and some artists, this
option was deemed not that useful. The use case was considered too
obscure so we'll remove it.
It is still posible to have this functionality by using the vertex
weight modiifers or manually clamping the weights.
This error was produced because now it is possible to have several Lattice modifiers and the Bake was removing the lattice data of all modifiers.
Now the data is only recalculated and removed for the current modifier.
Also some cleanup of comments.
Currently 3 of the printf lines use the format specifier "%lu" for data
of type size_t instead of "%zu". While this works, this creates compiler
warnings.
This diff fixes those warnings by using the correct format specifier.
Tested using MSVC, but should be correct on any compliant compiler.

- Use `use_` prefix for boolean properties.
- Use `_all` instead of `_everything`,
following existing conventions and the properties UI text.
- Use `object_instances` instead of old term `dupli` / `duplication`.
- Use `clip_plane` instead of `clipping_boundaries`,
matching the RegionView3D property naming.
Previously we could crash because we would not check if the modifier in
question actually was a line art modifier. We also did not query if the
modifier was disabled.
It caused some chaining errors when used in combination with image space
chaining. After some internal discussion, we realized it is not
useful as chaining in image space essentially does the same thing.
Only use non included objects for potential occlusion queries.
Don't calculate lines for them.
This fixes intersection lines appearing on objects not included by the
lineart modifier.
Changes include:
- Use `IFACE_` for UI labels set in the modifier panels
- Use a sub-sub-panel for transparency
- Fix grammar and spelling mistakes
- Use more natural user-friendly wording
- Make descriptions more specific and more useful
- Don't capitalize "line art" in descriptions (tooltips)
These changes are aimed at making the UI strings more consistent with
the rest of the UI and being more helpful to someone trying to understand
how to use the modifier.

This adds the LineArt grease pencil modifier.
It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.
This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.
These lines can then be baked and edited as regular grease pencil lines.

This patch adds a noise offset option to the grease pencil noise modifier.
It allows the user to animate the noise along the length of the stroke to create movement that is currently not possible.
It works by adding an offset to the noise table and adding the remaining floating point value to the noise table sampling.

Currently the grease pencil noise modifier seed value is under the randomize subpanel.
Moved the seed value outside of this panel because it doesn't only change the noise when using the randomize option. Moving the seed value prevents it from being hidden/greyed out so the user can manually keyframe it to control the noise animation.
