The way we were getting diff to apply to vcos from target object was just bad!
Also, fixed another related issue - negated scale would be clamped to nearly zero,
now only consider absolute version of size (we do not care about its sign here anyway).
This should be backported to 2.74 (with previous commit too).
The issue was caused by missing relations between smoke domain and flow/source
objects. This happened because smoke's modifier only iterated base objects and
ignored cases when flow/source could be linked to scene via dupli-group and
does not have real base.
The same seems to be still needed for fluid and dynamic paint modifiers,
will do it as a separate commit.

bounds indices of vertices.
Issue here is that if we copy edge customdata the MEdge data that were
previously written get overwritten, solution is to write indices and
flags last (probably writing flags is superfluous here).
The issue was actually affecting all data types that are not regular CDLayer ones, since by default
DerivedMesh references mesh data (verts, edges, etc. - modifying custom normals often implies
modifying edges' sarpness too).
Modfying edge/face sharpness etc. could directly affect the mesh in this case, **bad**!
So we detect whether we are copying data types that may affect non-CDlayers data, and whether
verts array of org dm is same as mesh one - in which case we copy the DM. This avoids
useless copying in most cases.
Note Edit Normals was quite obviously suffering the same issue.
Error in custom split normals work, non-autosmooth normals != vertex normals!
Loops from flat faces shall take normal of their face, not their vertex.
Tsst...
Nothing much to say here, basic tool to make normals point toward a target,
or to make them point 'outward' as if object was a spheroid (useful for game bushes etc.).
Also, forgot a big thank you to Campbell for the extensive review work he has done on this project!
- Add falloff types & curves (matching warp-modifier)
- Add uniform scale option,
important when adding hooks to non-uniform scaled objects,
especially for use with lattice objects which can't avoid uneven scaling.
This uses relative transformation set when the hook is assigned,
when measuring the distances.
This way it doesn't have to be stored as DNA runtime pointers or passed
down as a function argument. Currently there is now no property or
button to enable debugging, this will be added again later.
This helps to create some variation in a hair system, which can
otherwise become very uniform and boring. It's yet another confusing
setting in a system that should have been nodified, but only option for
now (broken windows ...)

framing method instead of the Frenet frame.
The Frenet frame is very succeptible to sudden twists along straight
sections of a curve where the second derivative (curvature) becomes 0.
This returns a general status (success/no-convergence/other) along with
basic statistics (min/max/average) for the error value and the number
of iterations. It allows some general estimation of the simulation
quality and detection of critical settings that could become a problem.
Better visualization and extended feedback can follow later.
This will allow us to implement moving reference frames for hair and
make "fictitious" forces optional, aiding in creating stable and
controllable hair systems.
Adding data in this place is a nasty hack, but it's too difficult to
encode as a DM data layer and the whole cloth modifier/DM intermediate
data copying for hair should be removed anyway.
as forces, velocities, contact points etc.
This uses a hash table to store debug elements (dots, lines, vectors at
this point). The hash table allows continuous display of elements that
are generated only in certain time steps, e.g. contact points, while
avoiding massive memory allocation. In any case, this system is really
a development feature, but very helpful in finding issues with the
internal solver data.
Not much to add, modifier uses same code as operator basically, only key difference
is that modifier will never create data layers itself, you have to use dedicated operator
for that.
