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.

The old value was too high. Now, the limit of pressure is 0, but anyway, the stroke will be always visible because there is a minimum thickness of 1 pixel.
Add a factor to determine the percentage affected.
This parameter is used to hide part of the stroke and to have a full control of how the points are displayed and not linked to current scene frame.

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.

Add new option to change the stroke hardeness. This option works at stroke level, not at point level.
Also replaced the "Both" name mode by "Stroke and Fill".

Both are doing almost the same and can be merged. This reduce complexity for user and less code to maintain.

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.
Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.

While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

- 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 is not 100% a bug but a design change. The old method used the object origin as pivot point for Scale a nd Rotation, so when you moved the stroke in edit mode, the whole array ittems where offset because the pivot point distance changed.
Now, before applying scale and rotation, the stroke is moved to object origin to keep the offset when scale or rotate, so these transformations are done in stroke local space.
A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.

This patch includes a modifiers that developed for NPR rendering.
- MultiStroke modifier that generates multiple strokes around the original ones.
Differential Revision: https://developer.blender.org/D5795
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 new option applies the opacity using the strength of the stroke instead to use the alpha channel of the material.

The vertex group filter has been removed because this filter is not logic in Material mode and must be valid only in Strength mode.
