* Merely a re-implementation of core split algorithm for BMesh, taking advantage of topological data available.
* This code needs valid loop indices, so added BM_LOOP support to BM_mesh_elem_index_ensure() & co.

Those derived meshes (used in Edit mode) were using simple sum of neighbor poly normals to get vertex normals,
while everywhere else in Blender we use weighted sum of such poly normals.

since enough bmesh operations can also take advantage of direct index lookups on verts/edges/faces.
developers note:
- EDBM_index_arrays_init/ensure/free -> BM_mesh_elem_table_ensure/init/free
- EDBM_vert/edge/face_at_index -> BM_vert/edge/face_at_index
- EDBM_uv_element_map_create/free -> BM_uv_element_map_create/free
- ED_uv_element_get -> BM_uv_element_get

add macros for initializing BMAllocTemplate's, also add assert on invalid use of bmesh_sfme()

remove the option to skip hidden faces in BM_mesh_normals_update, use openmp to speedup recalculation for high poly meshes.

normal-calculations and which operations require selection flushing.
eg, no need to flush selection after 'Smooth' tool, no need to recalculate normals after 'Select Similar'.

selected linked in face mode was crashing. (needs bmesh operator flags)
also some style edits, remove unused includes and change triangulate modifiers use_beauty to a flag.
|
|
modifiers that dont use bmesh operators can skip allocating it.

This commits adds a new function which can remap vertices/edges/faces of a BMesh in a new given order:
void BM_mesh_remap(BMesh *bm, int *vert_idx, int *edge_idx, int *face_idx)
|
|
BMEditMesh already stores an object pointer.
also fix for own mistake with mesh conversion refactor, shape key index was off by 1 when switching editmode.

verts/edges/faces in bm_mempool_init().

also correct bad assert() in previous commit.

Some function comments were in headers, some in the C files, some in both.
Moved function comments from headers into the C files.
