Last change to bevel had a check for what was supposed
to be an "on edge" new vertex being off the edge.
The test tolerance was too small. This fixes that.
There were loads of issues in the code still which are mow likely fixed:
- Hole resolver hook had memory leak -- it didn't free face with holes
when triangulating it.
- Original edge mapping didn't work correct. old code related on the fact
that loop order is not changing when constructing the MeshSet class, but
in fact it does change.
Currently used edge map for this because it was easiest way to do it now,
but after the release we're to change it. Main reason is that face mapping
is not correct as well (and it was never correct actually). So we'll need
to construct Mesh structures by our own to be sure we're using correct
original index mapping.
- Carve might produce faces with ears, which is forbidden in Blender.
it wasn't an issue in old integration because triangulation will remove
the ears. So for now simply added ears removing back as a hook.
But actual reason of the ears is to be investigated really.
This hook will only work for NGons, quads are assumed not be able to
have ears. So this additional hook shouldn't slow down things much.
- Carve's hole resolver produces duplicated faces in some cases. Still not
sure what is the reason of this. Code here is not so much straightforward,
this is to be investigated later.
For now solved the issue as own hole resolver which checks for duplicated
faces after the hole resolving.
The additional checks here will only run if the mesh actually have hole
and wouldn't introduce slowdown for faces which doesn't have holes.
- Made it so if edge user triangulation gets a split (for example, in cases
when this edge intersects with the second operand) it wouldn't be dissolved.
This prevents cases of crappy topology after dissolving in several cases.
- Edge dissolver didn't check for whether edge is a non-manifold. We couldn't
really dissolve open manifold edges.
The bad thing about this is that mesh triangulation might produce non-manifold
edges and they wouldn't be dissolved. Not worst case in the world, but would
be nice to have it solved somehow.
- Exporting mesh form Carve to Blender might have produced duplicated edges
in cases when several non-manifold faces shared the edge. This is also fixed
now.
- Mesh triangulation might have produced duplicated faces, which is really bad.
Fixed by keeping a track on which faces we've created and skipping adding new
triangle if we already have one.
This all might introduce some slowdown, but we're too close to the release now,
so would rather have it slower but robust. After the release we might look into
ways to speed things up.
This made loops in linked lists of uvedges from duplicate members
causing a hang. Now check all previous links before adding a new one. It
is not much slower in practice because non-manifolds are not that
frequent.
to wrong obmats of nested dupli objects.
Restoring obmats after BI nested dupli object rendering has to happen
in reverse order, so higher level omats are applied last.
If you have two overlapping NLA strips it automatically blends between them.
However it was also blending between the first strip and the rest pose
(e.g. 0,0,0 for locations and 1,1,1 for scale).
This is ok if the blend mode is Add or Multiply since then you are adding onto
the rest pose, but for Replace you want to be able to mix between two poses
and not take the rest pose into account at all.
What this does is that to not do any blending for the first strip if it has
blend mode Replace. If someone wants the old behavior (from bugfix commit
27d792fa9c) they can still make an action with the rest pose and use that
as the first strip.
Grease pencil straight line can still be enabled by first pressing D
then Ctrl and looks like there is no final consensus on key shortcut.
Better leave this as before and solve after release.
Implements a more flexible internal connect function for standard nodes
(compositor, shader, texture). Allow feasible datatype connections by
priority.
The priorities for common datatypes in compositor, shader and texture
nodes are encoded in a simple function. Certain impossible connections
(e.g. color -> cycles shader) are excluded by giving them -1 priority.
Priority overrides link status: If a higher priority input can be found,
this will be used regardless of link status. Link status only comes into
play for inputs with same priority.

Issue of this bug is that most part of fftw is not thread safe, only compute-intensive fftw_execute & co are.
Since smoke was affected by this issue as well, a global fftw mutex was added to BLI_threads.
Audaspace also uses fftw in one of its readers (AUD_BandPassReader.cpp),
but this is not an issue currently since this code is disabled in CMake/scons files.
There was another threading issue with smoke, we need to copy dm used by emit_from_derivedmesh(),
as it is modified by this func.

There needed to be a check that when a newly created point is
supposed to be on an edge, that it stays within the bounds
of either end of the edge.
This fixes the hole-in-cube example in the bug, but not
the boolean modifier one, which still needs more work.
Actually, was broken for any custom modifier name, since it was explicitly using 'Cloth' one. Changed to mimic other cloth pressets (wonder why this one was different!).
