Gpencil: clang format

GPencil: Change handle type while transform

For vector and automatic handles we need to change their type to free
and aligned respectively while transforming.

Use const& instead of pointers in Mesh class.

Correct geometry creation code with Curves.

Also make `Geometry` and `GlobalVertices` members of
`CurveFromGeometry` as `const &` to match with
`MeshFromGeometry`.

Merge branch 'master' into soc-2020-io-performance

Use FILE_MAX instead of PATH_MAX

Also, allow more vertices data points to be in int
strings.

Add SpaceInfoFilter to RNA

- add add, remove operators

Merge branch 'master' into greasepencil-object

Merge branch 'master' into lanpr-under-gp

Merge branch 'master' into greasepencil-edit-curve

Merge branch 'master' into greasepencil-object

GPencil: Change default Stroke thickness when convert curves

The thickness by default was using the old Draw Engine values and it was too thick in new engine.

Merge remote-tracking branch 'origin/master' into lanpr-under-gp

Merge branch 'master' into soc-2020-fluid-tools

GPencil: Remove color conversion when convert curve

In previous versions, grease pencil used sRGB and a color conversion was needed, but now all is Linear and the conversion changes the color wrongly.

WIP: Override preferences with command line arguments

- add separate save/restore operators for debug related options

Accept 3D UV vertex coordinates

The third one is still discarded.

Create new Geometry instance at the start.

Since the following is a valid OBJ file, a new `Geometry` instance
is always required.

```
v 1.0 2.0
```

Fix the nearest point containing cell when nearest is inside a tri.

Remove degenerate triangles before intersecting.
