When using the mask modifier loose edges could be added to the mesh.
These edges weren't marked as loose edges and wasn't picked up by other
areas of blender.
This fix recalculates the loose edges so they have the correct flag
`ME_LOOSE_EDGE`.

In some cases blender could freeze. When threads are blocked (waiting for other tasks completion) the scheduler can let the thread perform a different task. If this task wants a write-lock for something that was read-locked in the stack a dead lock will happen.
For task pools every task is isolated. For range tasks the inner loop will be isolated. The implementation is limited as isolation in TBB uses functors which are tricky to add to a C API. We decided to start with a simple and adapt were we need to.
During testing we came to this setup as it was reliable (we weren't able to let it freeze or crash) and didn't had noticeable performance impact.

Better to use more general term since in theory these forces can be used for smoke and liquid.

For now the "Simulation" modifier only exists for point cloud objects, because
we need this for the particle system. Right now, the modifier is doing nothing.
There is a new `DEG_add_simulation_relation` function that is used
by the modifier to make sure that the simulation is evaluated before
the modifier is executed.

For any modifier, the expected output when the input mesh is empty, is an
empty mesh. So this error message was useless, and could spam the
console in some usecases of the modifier stack...

After recent changes, simple solidify modifier would crash with Fill Rim
turned off and Bevel Convex emabled.
Also fixes that simple solidify would not set the bevel weight flag so the
next modifier could use the bevel weights.
Simple cleanup with do_rim is also included.

Add an option to solidify complex which will make faces which have thickness
controlled by vertex weights flat/even, and parallel to their original face.
For each face it uses the minimal weight assigned to its vertices to control
the thickness.
This will help users for example in architecture or basic CAD design by finally
making solidify work there at all if altering thickness is needed.

Adds a slider to solidify which allows the user to add bevel weight on the outside
or remove bevel weight from the inside.
Also includes a very small improvment for working with subsurface modifier where
the rim edge in complex solidify will now also have a chance to get a crease if
there is only two adjacent edges.

* Implemented the algortihm that would merge vertices to the weighted
center between them.
* Exposed the merge threshold to the user.
The new default tolerance is 0.0001 (versionning code ensures that
previous default value remains in use to avoid any change in existing

This commit mainly:
* Removes some uneeded dependencies to geometry of other objects (since
we only use positions of those objects...).
* Ensures `DEG_add_modifier_to_transform_relation` is only called once
per modifier (in one case at least it could be called twice).
* For modifiers using texture mask, only add dependencies to object used
to generate texture coordinates when there is actually a texture set.
No behavior change expected from this commit...

This adds the Voxel Mode to the current remesh modifier. It works
exactly the same way as the voxel remesh operator and uses the same
properties to control the remeshing. We can exand this with more options
in the future (fix poles, reprojection...)

This commit aims to add functionality to the surface deform modifier that
gives more control and allows it to work better with the modifier stack.
* Maintains compatibility with older files. The default settings keep it
so that the whole object is bound and vertex coordinates get overwritten
as the modifier currently does.
* Turns the deformations from an absolute vertex coordinate overwrite into
an additive offset from the vertex location before the modifier to the
resulting bound deformation. This gives the ability to control the
strength of the deformation and mix the deformation of the modifier
with the modifier stack that comes before it.
* Also adds in a vertex group with the invert option. This is applied after
the bind deformation is added. So the whole object is still bound to target,
and the vertex group filters afterwards what parts get affected.
I experimented with a version to only binds the geometry weighted to the
vertex group, but that would break compatibility with old files.
I may bring it in later as a separate option/mode for the surface deform.
With several fixes from @mont29.

vertex groups.
This commit gives the solidify modifier the ability to assign the newly created shell
and rim geometries to selected vertex groups. This expands the procedural control over
the modifier stack by letting users apply modifiers to the shell geometry without affecting
the original geometry.
This will be especially helpful for NPR users that use solidify to create backface
culling lines on their characters giving them the ability to add displace noise
and other effects.

Show control edges stores the control edges in the mesh which is
picked up by the draw manager. When applyng a subsurf (or multires) we
don't want that data present in the base mesh. Any rebuilding of the mesh
would overwrite the data anyway.
This patch introduces a new flag for applying modifiers
that can be checked to ignore storing display specific data in
the base mesh.

This commit adds the option to invert the resulting weights of the
falloff curve.
There is a workflow used by some to convert a texture mask into
vertex weights by using a custom curve and inverting the points.
This allows the same effect with a single click, and gives the modifier
more procedural functionality.
