- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.

This is a partial merge of some of the features from
the soc-2017-vertex_paint branch.
- Alpha painting & drawing.
- 10 new color blending modes.
- Support for vertex select in vertex paint mode.
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.
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.

Generalize logic for vert/edge/face selection:
- index cycling.
- selection bias with mixed modes.
Details:
- Edges now support index cycling (as verts/faces did already)
- Cycling over near elements is now only enabled when the mouse position remains the same.
- No longer do 2 selection passes to perform index cycling.
Fixes:
- Edges behind the view could be selected (surprising nobody reported!)
- Selection bias now only changes the element that gets picked without interning the return distance
(was buggy with mixed modes).
When mixing vert/edge/face with select-visible,
face selection could fail when not close enough to the center.
This also fixes a bug where the bias for verts over edges would
prefer faces over edges too, making edges harder to pick.
Mixing edge with other selection modes works more predictably now.
The purpose of this change is to add extra possibility to render engines and
export scripts to reduce peak memory footprint during their operation.
This new argument should be used with care since it'll leave mesh in not really
compatible with blender format, but it's ok to be used on temp meshes.
Unfortunately, it's hard to get scene where it'll show huge benefit because
in my tests with cycles peak memory is reached in MEM_printmemlist_stats().
However, in the file with sintel dragon it gives around 1gig of memory benefit
after removing the polys which would allow other heavy to compute stuff such as
hair (or even pointiness calculation) to not be a peak memory usage.
In any case, this change is nice to have IMO, and only means more parts of
scene export code should be optimized memory-wise.

Add simple uvs now does a cube unwrap and pack operation. Result is not
optimal by far but it should not result in crashes and it will be quite
usable for simple cases.
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
flush the selection on entering editmode instead (since the selection mode can be changed with another mesh).
is other tools leave the selection incorrectly flushed, those will need to be fixed so transform works as expected.
- give feedback on how many mirror verts succeed/fail (for select mirror, shape key mirror, weight mirror)
... when a mirror failed it was confusing and not obvious what was going on.
- slight change to select mirror, now center vertices will remain selected.
- speedup to EDBM_verts_mirror_cache_begin, cache customdata layer offset.
