This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.
Differential Revision: https://developer.blender.org/D8466
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This is often invalid, outdated or misleading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.
* bmesh.types, just allows access to BMVert, BMEdge etc.
* bmesh.utils, so far only added edge_split() function, this module will give access to mesh editing functions.
corrently allows to create and loop over verts/edges/faces, access selection and selection modes.
this is still WIP, access to face, edge verts is still missing, no access to UV's, no access to editing operations yet.
When the api is ready it will be documented by sphinx like mathutils, blf, aud.
