=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
Mirror merge two sides together to restore axial symmetry (like on a humanoid).
The symmetry is detected using the topological information from the Reeb graph. Eventually, it will have to distinguish between topological symmetry and potential spatial symmetry and only restore the former (for example, a human is always topologically symmetric, but we only want to restore the symmetry if the limbs are oriented in the same way).
- [#6112] is this an extrusion bug?
When extruding, x-mirror was giving weird behavior since the extruded vertice could match with their non-extruded counterpart on the other side.
The solution is to disable x-mirror (with a transform context flag, like disabling PET) in that case.
- External constraint setup calls (BIF_*) didn't setup some internal structs properly.
For the user, this resulted in some transform (extrude particularly) showing a full 3d vector in the header instead of a scalar along the constraint axis (this messed up num input a bit too, you could type values in unused axis).
Added a keyword argument for mesh.pointInside(point, selected_only=True)
This means only selected faces are tested when doing the inside/outside test, disabled by default.
- treat file passed as parameter the same as if loaded from UI if Blender isn't running in background mode.
- only set relative base as valid if file loaded successfully.
Fixed very old annoyance in alpha render: when using alpha textures images,
nicely premulled as Blender wants it, you still got dark outlines at the
edges. This because the blender shading pipeline also premultiplies.
Solution: de-premul image texture colors after sampling.
Scaled action times were getting calculated twice, which meant that translating a keyframe resulted in the keyframe "not following the mouse position".
NLA Window, Strip blending mode "Add" didn't work at all.
It was using very bad quaternion addition. Replaced with proper code.
For devs; new is the function QuatMulFac(quat, factor) which allows to
multiply a rotation with a value (make it rotate more or less)
Peach Request: Bone path lines are now drawn using two colours to show the parts of the path before and after the current frame. Those before the current frame are drawn darker, while those after are drawn in a blue colour.
Patch by: Teppo Kansala (teppoka)
This patch adds X-Axis Mirror support for the following tools:
- Delete Bone (X)
- Recalculate Bone Roll Angles... (Ctrl-N)
- Duplicate Bone (Shift-D)
- Clear Parent... (Alt-P)
- Move Bone To Layer (M)
compilation. Currently, it is not yet active by default, but
Genscher wanted to do some tests.
It can be used to distribute the computation load onto multiple shared-
memory CPUs by splitting the domain along the y-axis (assuming a
gravity force along z). However, there is no load balancing: so
if there's fluid only in one of the y-axis halves you will not get
a speedup for 2 CPUs.
- Added a fix for the memory allocation bugs #7120 and #6775. In
solver_init.cpp there are now several variables max___MemChunk
(line 692+), that set upper limits for various systems. The same
problem existed for mac & linux, but the limit is higher, so
it probably went by undetected. The windows limit is currently 1GB,
if the strange 700MB limit problems mentioned in the bug regports the
bugs persist, this could be further reduced. For 64bit compilations
this problem shouldn't exist anyway.
What's still missing is a display of how much the resolution was
reduced to fit into memory...
- And some minor solver code cleanup.
Mesh.c - mesh.faces.extend([..., smooth=True]) - smooth keyword argument, in a number of places was looping through all faces just to smooth them.
mesh_skin.py - smooth by default
Patch by: Matt Ebb (broken)
Currently in Blender, NLA action modifiers can work in very wacky and mysterious ways.
If an action is being modified with a path deform, when it reaches the end of that strip, it will snap back to the original un-modified location, regardless of whether the strip 'Hold' option is on. It's very frustrating to work with, and causes all sorts of problems - if you use a path to make a character walk from point A to point B, you generally want him to stay at point B, and not jump somewhere completely different, just because the strip ended.
This patch fixes this behaviour, and makes it much more sensible and predictable. There is a chance that this will break old files that were reliant on the old broken behaviour though, but I think it's definitely worthwhile to fix this problem.
Check the demo file in Blender 2.45 vs one with this patch applied - you can see the difference in behaviour.

The 'Only Needed' option for Auto-Keyframing now works better with a few of the different transform options.
Rotating/Scaling using a pivot point that is not the center of the Object/Bone (3d-cursor, active), also inserts location keyframes if the location also changes. If "Only Centers" option is activated, then only location keyframes are inserted.
This is much nicer than subdivision by angle but is somewhat less intuitive for users.
Added Bucket arc iterator, removing a lot of weird duplicated code in skeleton generator.
Relative shapekeys now allow to define the Shape it is relative to!
(It used to be relative with respect to the first key, which is still
default).
The reason for this feature is that keys don't always add together
well when they're all derived from the same base shape. A clear
example is hard to make... will wait for someone posting it. :)
* Added Windows specific implementation for fnmatch taken from GNU/MINGW/MSYS C library
* behaviour should now be the same as under Linux and other OSs
* changed filename for fnmatch.h to ensure we include the correct one if we link with the included implementation
* tested compile with MSVC 7.1 and gcc(MinGW-5.1.3) on Windows.
removing vertex groups was broken, the function being called was for editmode, this would remove the vertex group but apply the weights from the removed group to the next vertex group.
- error fix: overall weight group value was used inverted
- added "Inv" button to make weight group work inverted
- added bigger, more clear Multi Modifier button

- Seperated StripData into
StripData
TStripData
where StripData holds only image-filenames and TStripData holds
the working information needed for ImBuf caching.
=> Large drop in memory usage, if you used a lot of movie and meta strips.
=> Fixed bugs in "duplicate" on the way (imbufs where copied around without
taking reference counting seriously...)
=> Code is much cleaner now
- Added defines for TStripData->ok
Finally figured out, what the magic values ment and named them properly :)
- Got rid of Sequence->curelem.
Reason: very bad idea(tm) for multi threading with more than one render
thread. Still not there, but this was a real show stopper on the way.
- gravity (like particles)
- follow parent (like gravity but use the parent normal)
- limit the number of twigs on each branch
- limit the radius that a twig may be placed on a branch
- trim the base of branches in a way that better deals with small branches on large branches
This allows to mix between the result of 2 modifiers, with both
using the same input state. This is useful for having a mesh deform
and armature deform working together.
However! This functionality could have been presented better...
this is actually Node editor stuff!
Now it works by adding a "MM" button, next to the "overall vgroup"
option. If MM is pressed, the input of this modifier is the same as
the input of the previous modifier.
Only the armature modifier has this option now...
* Mesh.c bugfix, "mesh.verts = None" didn't set the mesh->mselect pointer to NULL, wizard_curve2tree so would crash when in editmode.
* Texture.py - MTex.uvlayer doc was missing
* buttons_shading.c - Stencil tooltip was stupid.
