The old modifier had two modes, but it is better to keep separated as meshes.
The UI has changed to be more consistent, including a new column type of modifiers.
Note: The logic has not changed with the previous version of the modifier, just is a split on two modifiers..

Create dot-dash effect for grease pencil strokes. User can manually edit the length, gap and styles for each segment of dashed lines.
The values in each segment can all be key-framed to make animations.

his new modifier allows to generate weights base on:
* Angle of the stroke relative to object or world orientation. For example, if the value is 90, the maximum weights will be for vertical lines and minimum for horizontal lines.
* Distance to Target object. The distance calculated is normalized to get valid weights between 0 and 1.0.
The weights are created in an existing vertex group and the data can be replaced or mixed with the existing value to combine different weight effects. The minimum parameter, allows to define the minimum weight generated. This is useful to avoid very low weights.
The generated weights can be used in any modifier. For example, the angle weight value can be used to mimic FreeStyle Caligraphy modifier using the weight with the thickness modifier.
Also some modifier has been changed to inlude a new option to use the weights as factor of the effect.
As result of this change, the fading option has been removed from Thickness and Opacity modifiers because this can be done using the new modifier, it's not logic to repeat the same.

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.

Remove DNA headers, using forward declarations where possible.
Also removed duplicate header, header including it's self
and unnecessary inclusion of libc system headers from BKE header.
This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule. This should be the final commit of the series of commits that
addresses this particular rule.
No functional changes.
Before, the material name was used to filter the effect of the stroke, but after the last changes in the ID code, now it's not working.
After talking with @severin, we agreed to replace the material name with a pointer. Also, this fix a design issue when the materials were linked.

This patch aims to add a new modifier for grease pencil objects that gives more control over the strokes texture UVs.
There are 3 modes.
1 Control the stroke texture UVs alone
2 Control the fill texture UVs alone
3 Control both the fill and stroke texture UVs
For the stroke texture UVs there are 2 options for fitting the texture to the stroke.
1 The texture uvs are kept a consistent length how it currently is set by default.
2 The uvs are normalized to fit the length of the stroke regardless of how long or short it gets allowing the texture to fit the length of the stroke.
There are then 2 controls to scale up and down the uvs and an offset value that allows moving the texture along the stroke.
For the fill texture UVs it includes all of the transformational controls. Location offset, scale, and rotation.

This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes.
Also, a huge code cleanup has been done at all levels.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.
This patch includes a modifiers that developed for NPR rendering.
- MultiStroke modifier that generates multiple strokes around the original ones.

When apply the modifier a new material is created, but it was assigned wrongly. The problem was the index was base 0 already, so subtract 1, got a wrong value.
- The ambiguous term 'handle' was used where 'ensure'
is typically used (get or add when missing).
- Rename `current` to `active`, all `current` functions which were
also ensuring.
- Clarify what is being operated on, using `BKE_gpencil_object_*` for
objects, `BKE_gpencil_brush_*` for brushes.
BLI should always comes first, before DNA, BKE etc. And
`BLI_utildefines.h` should come before any other BLI (since it's some
sort of system include really, among other things...).
Thisi should help to reduce the noise in patches when adding stuff
like uint64_t members to DNA structs... ;)
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.
Fixes T58632: Particle don't update rotation settings
The old name Instance was logic when the modifier created new object instances, but now works equal to mesh Array modifier, so the old name was not logic and must be Array.
Also added a Object to use as offset similar to mesh Array modifier.
This commit adds a new armature modifier for grease pencil. The deformations are done reusing the mesh deform routines.
There is also a new operator in weight paint mode to help the artist to generate weights base on armatures. This operator is required because 2D animation workflow is not equal to meshes when parent an object to armatures.
In the drawing engine has been added the option to handle the Fade object parameter used in armatures to see the strokes while move the bones.
When rename bones, all related data of grease pencil is renamed too. This not only affect new armature code, but also layers parented and hook modifiers.
Thanks @aligorith for his review and help.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
