DNA data + modifier for storing persistent hair data.

This stores basic hair follicle data, rather than full fiber caches
(which should only be generated for render data).

Note that deformation by strands will just be one possible way to generate
hair fibers, so strands should be kept separate from the hair follicle data somewhat.

Merge branch 'blender2.8' into greasepencil-object

VFX Wave modifier uses PI range

The sinusoidal curve uses a loop between 0 and PI to get better and smooth result

Fix problem of VFX double drawing

The vfx pass needs a separate framebuffer to avoid double drawing of the strokes.

If necessary, a full copy of the initial texture is done to be used by all vfx modifiers.

Fix memleak in Weighted Normals modifier when autosmooth is disabled.

Fix error in build by including limits.h

Fix Cycles CUDA adaptive megakernel build error.

Rewrote the code for sharp edges on weighted modifier.

Merge branch 'master' into soc-2017-normal-tools

Fix broken API doc generation: Partially revert rBa372638a76e0

Making those arrays static remove them from exported symbols, which
breaks API doc generation script.

To be backported to 2.79 branch.

New VFX Wave modifier

Distorsion using sinusoidal wave

Cleanup: Reorganize code

fixed texture painting brush issue

Prototype hair deformers for generated detail like clumping and curling.

Currently only clumping and curls are implemented. There is no proper input
for the parameters yet, these are just hardcoded atm. Eventually the hair system
should either define uniform values from hair system settings or enable per-fiber
values using a material or other node-based input.

New VFX Gaussian Blur modifier

This modifier works only at viewport level and cannot be applied.

Manipulator: experimental lamp positioning tool

- New manipulator tracks lamps to position under cursor.
- Works with multiple lamps, keeping relative offsets.
- Holding Ctrl moves the lamp.
- Access via manipulator or Shift-T.

Code could be improved, but like to get feedback from users.

minor fix: forgot to update frame in display when converting to keyframes

fix for wrong centroid calculation when re-using existing mesh-islands

this affected the physics mesh and the convert to keyframes function, which created incorrect results.

Cleanup: Reorganize code

WIP: Basic structure of VFX Gaussian Blur

This is the first step to implement a system for adding VFX modifiers that are applied to viewport and not to strokes
