* The symmetrize operation makes the input mesh elements symmetrical,
but unlike mirroring it only copies in one direction. The edges and
faces that cross the plane of symmetry are split as needed to
enforce symmetry.
* The symmetrize operator can be controlled with the "direction"
property, which combines the choices of symmetry plane and
positive-negative/negative-positive. The enum for this is
BMO_SymmDirection.
* Added menu items in the top-level Mesh menu and the WKEY specials
menu.

updating data was only being done on the active object but sticly was being calculated for the selection.
split this into 2 operators, one that works on the selection and another that operates on the active object - so we can have a button in the mesh panels that calculates sticky.
also note that there was no way to calculate sticky from the UI - perhaps this feature should die a quiet death?
anyway - it works better then it used to for now.
currently can remove sticky/mask/skin vertex layers.
regarding the skin layer - while adding and removing the modifier normally works fine, its not 100% reliable since the mesh may be linked into another scene, or be a linked duplicate and the object with the modifier deleted.
Now only one operator. Same options for vertices, edges and faces (so adds edges sorting, and some options to vertices sorting).
Face sorting should behave as previously. However, XSortVerts won’t pack anymore selected vertices at the begining of the vert array (as it used to), if you want such behavior you’ll have to first run SortElements with Selected action.
Also added bug ref I forgot in r46354 (armature.c).
- makes wireframe from faces.
- options similar to inset (even offset, relative scale)
- copies face settings and loops (uvs, vcolors)
- optionally replaces the existing geometry.
from user freedback it seems there are 2 use cases, both valid.
* Select geometry and cut the selection in half (as 2.4x worked)
* Point-to-point define the faces to cut, dont cut through everything (only cut what you see).
With the second, since you are already selecting the edges to cut and snapping to them. only cutting the selecting is limiting/annoying.
Modifying these options while the knife tool runs doesn't work well, so expose under 2 keys, K, Shift-K.
- Even option (like solidify even option)
- Relative option (insets based on lengths of surrounding edges)
TODO: merge tares when 2+ face corners meet but don't form a contiguous region.
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
* made bmesh_structure.h function names more consistant.
* remove unused code in bmesh_structure.c
* removed 'Edge Flip' operator (missing from bmesh but looked into trunk feature and dont think its worth keeping).
* tagged some BMESH_TODO's
This is a kind of simplification/cleanup tool which joins adjacent faces and edges based on the angle.
I've written this as an exercise (since I havnt written a bmesh operator before), and because quite a few users were asking for the dissolve operator to be extended, but I think this kind of functionality needs its own operator.
access from specials menu and mesh menu.
notes
* this exposed a bug in angle_v3v3v3(). will merge fix into trunk after release.
* added utility function BM_vert_edge_angle(), to get the angle between 2 connecting edges of a vert.
`_set` suffix was used in two ways (confusing)
* to set a flag to be enabled.
* to set a value passed as an argument.
now use enable/disable rather then set/clear for functions which change flags.
also remove BME_weld.c, the file didnt contain much code and the current extrude works well
- 2 new navmesh operators, reset and clear navmesh data.
- rename operators to be more consistent with existing names.
- some minor edits to draw function, was getting the custom data for every index when it already had the array.
and select loose verts/edges:
----------------------------------------------
Split select by number of vertices and select
loose verts/edges into seperate functions.
Previously select by number of vertices was
also accessed through two different UI items,
"Select Quads" and "Select Triangles". Now
it is one function with a integer property
for selecting the size of the face you want
selected.
Also added an option to modify the behavior
of the selection. Can now select whether you
want to select faces that have vertices
equal to, less than or greater than the number
of vertices in operator property.
1. Removed pinning, at least until after trunk
reintegration (it's a usefull feature, but
incomplete).
2. Ripped out the subclassing code I originally
wrote so bmesh would be more usable for modifiers
(I ended up improving CDDM instead).
3. Inlined some of the macros in bmesh.h, still need to
do the macros in bmesh_operator_api.h.
4. Removed the BMESH_ITER_*** macros (except for BMESH_ITER_INDEX).
They were too clunkly to be worth it.
