Summary

Mesh data transfer (data here being either real CD layers, like e.g. skinning weights, UVs, etc., or 'fake' ones, like e.g. vgroups, shapekeys, but also edge crease, smooth/sharp/seam flags, etc.) is subdivided in several sub-modules:

Mapping between mesh elements (verts, edges, polys or loops), in BKE's mesh_mapping.
Mapping between data layers (for non-singleton data types), mostly handled in BKE's data_transfer and customdata areas.
Transfer of single data layer, mostly handled in BKE's customdata area.

Note mapping supports complex 'Islands' cases, where you need all elements of a given dest entity to map into a same source island's elements - only used and implemented at Loop level currently (UVs, and in near future custom loop normals), but design should allow to extend it to other mesh types if needed.
Note multi-layers data mapping and data transfer itself use some generic code, but can be overriden as needed (done for vgroups in this patch).

Additional possibilities/refinements include (only relevant for a subset of data types):

A way to filter which elements of destination we actually want to affect (through a vgroup, and/or above/below threshold).
A way to alter destination elements' data in other ways than mere replace (add/sub/mul/div/etc.).

All this is designed to be both easy to setup (code-wise) for simple types, and yet flexible enough to be usable by complex/weird data types like vgroups and shapekeys. For now, it is only expected to work in Object/modifier contexts, not quite sure whether having this in BMesh would be that much useful?

Available as both a modifier and an ObjectMode operator.

Open questions:

UI: mostly, modifier one - in fact, I’m wondering if allowing to transfer several data types at once is such a good idea... Pro is, it avoids recomputing mapping data, but it makes UI rather confusing...
Mapping modes: not sure all implemented ones are that useful. And I know a few that are needed (like loop projection along vertex normal, not loop normal). But I think this can be done later too, that would not affect general design.

Remaining TODOs (not considered blocking for master inclusion, imho):

Shape Keys (not handled, have to see how this merges with gsoc work too).

Checked the patch, (first pass)

Overall, it seems like this is heading in a good direction, but theres enough issues remaining too that need some attention.

Usability

The modifier is showing many options which probably wont apply in many use cases (copying vgroups for example - 2/3 of UI has edge/face options still),
This _is_ difficult to present to the user in a straightforward way.
Anecdotal evidence - recently I talked to 2 guys on the gooseberry team about weight-copy feature, and neither managed to get it working usefully, this is strange since whenever I test it, it works fine... and I think its not _so_ hard to use, just to say conveying what happens here to users needs to have some consideration.

Feedback from others would be good here,
(own suggestion) - have a checkbox for each mapping mode (vert/edge/face-corner/face), then at least if the user really needs they can enable all... better solutions may exist though

By Position (could be confused with 3d position), better use By Order ?
Nearest Corner And Best Matching Face Normal - (maybe this is great to have, but are these tested for real-world use cases?, lots of stuff we _might_ want, but maybe not needed.. nice to see examples where these options are needed)

Functionality

I'd like to test this more when its more stable, but some quick observations.

Mix Mode, Having the option to 'Replace' would be useful.
'Freestyle Flag' should be 'Freestyle Mark' or 'Freestyle Settings' (flag is internal naming).

A more general concern is that this is both a modifier and a tool, where tools are acceptable to be slow & give high quality results and modifiers are expected to stay fast & interactive. Just a comment & no action needed, but its something to keep in mind how to manage settings if some high quality data-transfer method doesn't work so well for modifiers.

Code

Getting some asserts just testing the modifier. (as well as the one mentioned)
DerivedMesh.c:1455, dm_ensure_display_normals(), at 'CustomData_has_layer(&dm->polyData, CD_NORMAL) == 0'

Got this crash copying vertex groups:

I'd like to go over this patch more, but as first pass review, think there is enough feedback for first-pass

source/blender/blenkernel/intern/mesh_mapping.c
896	The modifier can trigger this assert, ideally the modifier would check beforehand and display error text. (and not call `BKE_dm2mesh_mapping_verts_compute` in this case)
2063	This isnt so efficient to check `isect_point_poly_v2` (which in turn loops over all points), `fill_poly_v2i_n` is better suited to this task. (much faster, used for lasso-fill drawing)

Thanks for that first review, Campbell! Addressed most of raised issues (along a few others) in branch now.

Inlined are some further comments.

Gave it a try, think UI is much better now. But of course, more feedback here would be great, this is a tricky part.

- Nearest Corner And Best Matching Face Normal - (maybe this is great to have, but are these tested for real-world use cases?, lots of stuff we _might_ want, but maybe not needed.. nice to see examples where these options are needed)

Hmmm… Tbh, I’m not sure all proposed mapping modes are useful, but that one is for sure. Thing is, once you have found nearest vertex, there is a good chance all loops of this vert share the same normal (smooth vertex), so using face normal as discriminant is often the best solution here.

Code
Getting some asserts just testing the modifier. (as well as the one mentioned)
DerivedMesh.c:1455, dm_ensure_display_normals(), at 'CustomData_has_layer(&dm->polyData, CD_NORMAL) == 0'

Yeah… Well, enhanced normal handling in the patch quite a bit. But this remains tricky too, I think computing poly normals and just throwing them away afterwards is stupid, in the DM context (this is not a cheap operation). Consequently, I’ve disabled that assert for now.

I’m not quite sure this is right/safe though, maybe we'd rather just always (re)compute that data for now, and let proper poly/loop normals caching for another refactor?

Got this crash copying vertex groups: P164

Tried to reproduce, no luck so far. Traceback is also rather odd, as if CustomData_duplicate_referenced_layer() got called with wrong number of elements, but I cannot see how that would happen of hands. Crashing file would help here I guess.

In master now (rB88ee44a9ac367, rB2e72d756c49, rB17941860530, rB62cc4bab0838, rB58d7153c6c4d5, rBee4453f08369d and rB79d8617424daed).
