In fact, any type of baking might have caused holes in mesh.
The issue was caused by zspan_scanconvert() attempting to get order of traversal
'a-priori', which might have failed if check happens at the "tip" of span where
`zspan->span1[sn1] == zspan->span2[sn1]`.
Didn't see anything bad on making it a check when iterating over scanlines and
pick minimal span based on current scanline. It's slower, but unlikely to cause
measurable difference. Quality should stay the same unless i'm missing something.

Just using same code for distribution for face/volume as the one
changed/used for vertices since some months.
Note that this change is breacking compatibility, in that distribution
of particles over faces/volume may not be exactly the same as
previously.
- Use indices instead of character args.
- Use numbered macros instead of variadic args.
Parsing using rtags used over 11gb of memory. While this should be
resolved upstream (report as #1053), the extra complexity didn't give
any real advantage.
There was some invalid state in the screen here, some areas had
sa->full set even though no screen was maximized, which then caused
a restore from the wrong (empty) area, which then led to spacedata
being empty and a crash.
This fix properly clears the sa->full after restore, and also fixes
existing .blend files in such an invalid state.
Only the camera from View3D.localvd is used,
other pointers may be invalid.
Longer term we should probably clear these to ensure no accidents.
For now just follow the rest of Blender's code and don't access.
Baking rigid body cache was broken if some cached frames already
existed.
This is just a band aid for release, the logic need to be looked into
further.
Operators and their properties are two different types
Previously both operators and their properties are added
causing C operators to access the properties, Python the classes.
Favor consistency in this case so only Python classes are added.
A single diagonal axis was used for sorting coordinates,
the algorithm relied on users not having vertices axis aligned.
Use BLI_kdtree to remove doubles instead.
Overall speed varies, it's more predictable than the previous method.
Some typical tests gave speedup of ~1.4x - 1.7x.
For example, if you have two keyframes:
k1 = 1px, k2 = 10px
it was doing:
1px, 9px, 8px, ..., 3px, 2px, 10px
instead of:
1px, 2px, 3px, ..., 8px, 9px, 10px
