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This is often invalid, outdated or misleading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.
For simple cases bitmasks were OK, but didnt work for vert/edge, vert/edge tests.
Tag verts instead, makes logic easier to follow and gives minor speedup.
running BM_CHECK_ELEMENT was taking over 75% of the time to subdivide a mesh, since this only reports errors, and is so slow - only run this on non-release builds.
- remove unused vars
- no need to hard code version number for collada.
- cleanup some typos in comments.
- movieclip_calc_length was passing arg which should be unsigned to BLI_stringdec()
- BM_mesh_normals_update was looping over all faces to find the largest one, this is no longer needed.
- calculating a face normal was looping over every faces corners twice, now only once - using the loops directly (not an iterator).
- face vert locations were being copied an array, now use directly.
- calculating the normals would copy a float vector for the next point in the face, which was never used (only current and previous used).
- was copying vectors to compute the normal, now just assign the float pointers.
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
* change BMO_elem_flag_* defines to inline functions.
* BMO_slot_map_insert() is too big for an inline function - un-inline it.
* remove redundant casts.
