Before, the modifiers were evaluated in Draw Engine and this required to calculate a factor to increase the VBO size.
Now, the modifiers are evaluated in Depsgraph and the Draw Engine receives the evaluated stroke with the final number of vertices. As the number of vertices is the final value already, if Draw Manager increases the number with the modifiers only increases the memory with empty space because never would be used. This commit removes this double calculation, reducing the memory usage and removes a loop to calculate the size by modifier too.
Also, the function getDuplicationFactor() has been removed because is not required anymore.

This commit adds a new filter by material using the name and not only the index.

Prior to this commit: If the Grease Pencil Thickness modifier is set to Normalize and a Vertex Group is selected, the thickness of all strokes are effected when changing the Thickness parameter. Points on strokes are only normalised (= pressure set to 1.0) if they are part of the Vertex Group; the strokes themselves may still change thickness.
With this patch: If Normalize is selected with a Vertex Group, Blender now pre-checks each stroke to determine whether it has vertices within or outside the Vertex Group. If all the points on the stroke belong to the Vertex Group, it normalises the whole stroke to a uniform thickness. If some or none of the points of the stroke belong to the Vertex Group, the stroke is now left as is.

This commit adds the frame to deformStroke Callback as a preparation for new modifiers that will need this variable.
Actually, the existing modifiers are not using the frame.

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... ;)

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

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This is often invalid, outdated or misleading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.

This is part of T57829.
Reduce the number of batches used to only one by shader type. This reduces GPU overhead and increase a lot the FPS. As the number of batches is small, the time to allocate and free memory was reduced in 90% or more.
Also the code has been simplified and all batch management has been removed because this is not necessary. Now, all shading groups are created after all vertex buffer data for all strokes has been created using DRW_shgroup_call_range_add().
All batch cache data has been moved to the Object runtime struct and not as before where some parts (derived data) were saved inside GPD datablock.
For particles, now the code is faster and cleaner and gets better FPS.
Thanks to Clément Foucault for his help and advices to improve speed.

New modifiers have thsi default value.
|
|
|
|
Now the modifier can be filtered using the new layer index.
Also changed panels to put layers and passes filter always at the end of the panel.
|
|
This modifier allows to offset the keyframe animated to get more variations in the animation when reuse the same datablock.

Name hinted 'vertex index', where it's the index of the vertex group.

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

https://code.blender.org/2018/07/grease-pencil-status-update/
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.
