This is the (big!) core of mesh transfer data, it defines a set of structures
to represent a mapping of mesh elements (verts, edges, polys of loops) between
two arbitrary meshes, and code to compute such mappings.
No similarity is required between source and destination meshes (though results
when using complete different meshes are rather unlikely to be useful!).
This code is not bound to data transfer, it is defined to be as generic as possible,
and easy to reuse or extend as needs arise.
Several methods of mapping generation are defined for each element type,
we probably will have to adjust that in future (remove useless ones, add
new ones...).
For loops, you can also define islands (for UVs e.g.) so that loops of a same
destination polygon do not 'spread' across several source islands.
Heavily reviewed and enhanced by Campbell, thanks a lot!
`INSERT_FAST` implies you call `calchandles_fcurve()` at the end...
For now, since we do not store edited FCurves nor can we get them easily
(requires RNA...), just update handles of all fcurves, it's much more
performant than removing usage of `INSERT_FAST` anyway.
You can now use lower-level '_ex' versions of bvh creators to only use part of
the mesh's elements in the BVH, and/or create bvh from non-DM sources.
Needed for transfer data.
Note edges extend version of bvh creator is not added here, not needed so far.
and graph editor.
This was a tricky commit that was not so straightforward to make work.
The information for bones is not easy to come by in the animation curves,
however we do have some string manipulation tricks to make it happen.
Testing in gooseberry worked for the rigs there, commiting to master now
Propper fix reverting most of rB60e70c0c6014e5, which was only partial specific fix.
This code uses generic `BKE_id_lib_local_paths()` func to handle all possible paths.

Also cleanup extrude code.
- remove normal calculation.
- remove return values for transform type.
- use enums.
Thanks to Psy-fi for finding the initial fix.
Generally for build systems, libraries that do not depend on other
libraries, such as system libraries, OpenGL etc always go at the end.
We could even get rid of some duplicate dependency libraries here but
auto duplication by build systems and differences between OSs make this
difficult.
GTest still duplicates all libraries twice to solve some issues which is
weird (maybe libs are not sorted correctly for some reason? needs
investigation)
Simply have to rebase onto main filepath when copying, if source datablock is lib and path is relative.
Afaict, only affected Image and Text datablocks. MovieClip would also be a candidate, but has
no copy implemented currently.
Instead of getting fancy this time, we'll just use Mahalin's simpler
fix. This may have slight performance impacts, but it is a lot simpler
than the previous fix and shouldn't cause as many bugs.
Sorry about that, should have checked this stuff more, with Internal material
renders are very fast (unoticable), but with Cycles it can take (a lot of) time,
like several minutes or more.
Will probably fall back to a dedicated operator users will have to fire themselves
when they want previews in their files.
This partial reverts rBd800cffaf10cb7, but fixes T40435 (Background label is not
redrawn).
It now isn't possible to use single modifier keys as shortcuts anymore. But this
is something that's not really useful at all, since it breaks more than it allows.
