Corrects mirror syncing for invert, levels & smooth.
Note that the code changed to process mirroring even if both verts are selected,
since group flipping can mean that is still meaningful.
Since weight_other is equal to weight_accum_prev[i_other], the original
lines actually are no-op. The visible effect is that when smoothing just
two vertices with weights 1 and 0, the expand value has no effect until
it reaches exactly 1. This change makes it gradual.
It also fixes another issue (crash) related to symmetric editing.
Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index
as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time...
This patch mostly fixes particle editing mode:
- Adding/removing particles when using generative modifiers (like subsurf) should now work.
- Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work.
- X-axis-mirror-editing particles over ngons does not really work, not sure why currently.
- All this in both 'modes' (with or without using modifier stack for particles).
Tech side:
- Store a deformed-only DM in particle modifier data.
- Rename existing DM to make it clear it's a final one.
- Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches.
- Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM
when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface
from an final DM tessface index).
Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway),
it's more like some urgency bandage. Whole crap needs complete rewrite anyway,
BMesh's polygons make it really hard to work with current system (and looptri would not help much here).
Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.

We can now use 'generic' data transfer instead.
Note new one is not an exact replacement, it should be able to do
everyting old op could do though, and more.
Along with some minor cleanup and simplifications.

It was using the modified mesh for the vertex coordinates, and the unmodified mesh
for the vertex weights, which can't work and crashed in some cases, now it used the
modified mesh for both.
Perhaps an option should be added to indicate if you want to transfer from the
unmodified mesh or transfer to the modified mesh, but I think this fix makes it
works as intended when this was implemented.
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
This option is needed when vertex groups are used for both armature
deformation and the other purpose such as influence of mesh modifier.
Thanks to Campbell for code review!
