Also I noticed there's a check on strip.type == 'EFFECT', which can never be true because strip.type actually contains the type of effect, e.g. "GLOW", "ADD" etc. Not a big problem currently because it's not used.
This patch add SPH (Smoothed Particle Hydrodynamics)fluid dynamics to the
blender particle system. SPH is an boundless Lagrangian interpolation
technique to solve the fluid motion equations.
From liquids to sand, goo and gases could be simulated using the particle
system.
It features internal viscosity, a double density relaxation that accounts
for surface tension effects, static internal springs for plastic fluids,
and buoyancy for gases.

This is a commit of the core fluid physics. Raul will work on proper
documentation soon and more features such as surface extraction from
the particle point cloud and increasing stability by sub-frame calculations
later.
experiment and turn out to work poorly because it does not preserve
rotations, so I've just removed the option now. Alternative is to use
a solidify modifier on the cage mesh, which will usually give better
results.
This commit fixes reports #21638 and #21818, which were both also Durian feature requests.
Cbanges:
* Added new default setting for the type of handles created when creating keyframes. This can be found in the user-preferences, and is used whenever existing keyframes aren't being overwritten (instead of the value being always taken from the keyframes either side, #21638).
* When keyframing over existing keyframes, only the values will be changed. The handles will be offset by the same amount that the value of the keyframe changed, though how well this works in practice still needs to be tested more thoroughly (#21818, already fixed earlier, but this commit is the full fix).
* When 'free' handles are added by default, they are offset to be +/- 1 frame on either side of the keyframe so that it is obvious that they can be moved. However, they just take the same value of the keyframe since this is easiest.
* Properly initialising handle colour defaults for 3D-View and Graph Editor. Graph Editor's theme userprefs also show these settings now, though the layout is really quick hack-style.
* Fixed all the dangerous code added in 27907. Using the code there, scripters could corrupt animation files in ways which would render them useless, with channels not appearing in any animation editors, and others not getting evaluated at all.
* Partial fix of bug 21818, by disabling destructive replacement of keyframes. Will followup this commit with a more comprehensive commit which gets rid of the rest of the problems, by incorporating some requests from Durian team.
* Fixed problems with users being able to see+edit the name of the active Keying Set in the Scene buttons. There is still a bug though with the list widget given how the indices are now interpreted...
Emulate 3 button mouse is now disabled when Left mouse select is used, to
prevent keymap conflicts. Configs for single button macs etc we can do with
keymap presets.
* Some cases of struct name being set where it shouldnt have been.
* Spelling: wich --> which
* Copy and initialize uv modifier scale, remove unneeded enum.
* Ability to pin any object into the context.
* Update uv window while transforming (useful when used with UVProject modifier)
* Patch by Wahooney, so new template's are internal text and dont get saved over
by mistake.
* Fix for https://bugzilla.redhat.com/show_bug.cgi?id=572186
Bug 572186 - [abrt] crash in blender-2.49b-5.fc12: Process
/usr/bin/blender.bin was killed by signal 6 (SIGABRT). Original fix submitted
by Jochen Schmitt.
* [#21816] bpy.data.add_image has stopped working on Windows. moved to
bpy.data.images.load(), missed this call.

mask, also avoid making vertex groups if they will not be filled.
* Add back image pin option in image editor header.
* Fix deep shadow not respecting Cast Buffer Shadows option.
* Tangent space normal map baking should work again now.
* Fix a problem with particle duplis, due to own bugfix for #20350,
the problem for that seems to be in dupliverts, not particles.
* Fix external multires data link getting lost on exiting editmode.

to specify different spring lengths.
Implementation is quite ugly because the shape key has to be pulled
through the modifier stack somehow, need a more flexible data mask
system to solve this properly.

Theme colours were getting overwritten on startup with defaults (as in 2.4
system). Changed this to allow changing the default theme, and added a
'Reset to defaults' operator in user prefs. Perhaps next step to look into the
py presets system for themes too (nice and easy to share).
If you're using a custom B.blend you may get some strange theme colours on
startup if they weren't saved properly before. 'Reset to default' button in theme
preferences should fix it back to defaults.
Stopped curves 'caps' properties from being greyed out when the curve is 3D -
there's the totally obscure feature where turning off 'Front' and 'Back' turns the
3D curve into a tube.
Would really like this feature to be implemented in a less bizarre way, but
for now it should be enabled in the UI at least.
For some reason, __import__ doesn't recognize the cfg folder as part of the part.
Using exec("import " ... fixes that, but should be investigated further.
Also force post process off.
This is a partial fix for Bug [#21410], there is still the problem that loading back multilayer exr as render results doesn't load the composited result correctly (bug is assigned to Brecht). The results are still ok when downloaded outside of the render engine, so there's a work around for now.
This commit removes the Old Track method (used to be found under Object -> Animation -> Track), with all existing instances of this being converted to Track To Constraints. In fact, while performing this removal, I found that this was supposed to have happened in version 2.27 already, but for some reason the options were left in, and this function managed to survive for a further decade.
I've left the tracking axes around still, since it seems some curve tools still use that. However, that usage should probably get faded out in future too?
Misc notes:
* Fixed compiling error with constaints from harkyman's Maintain Volume patch.
* Subversion of 2.52 now bumped up to .2
This commit restores fluid sim baking functionality in 2.5, it's been on the todo for
a while, and was previously almost completely non-functional. The old
code was quite complicated and specific to the 2.4 animation system, so I've
pretty much rewritten most of it.
This includes:
* Animated variables work again - just key them in the UI. Non-animateable values
should be already set non-animateable in RNA, hopefully I got them all.
Available are: Domain Gravity / Domain Viscosity / Object loc/rot/scale /
Object initial velocity / Deforming meshes / Fluid control Attract strength /
Fluid control Attract radius / Fluid control Velocity strength /
Fluid control Velocity radius / Object Active status (checkbox next to fluid type)
The Domain time scale is still not yet implemented.
* Fluid sim now use global scene units data by default - when enabled, the
scene's global gravity value is used and when units are set (metric/imperial)
the simulation real world size is taken from the object's actual measurements.
* The baking process is now done in the background, using the nifty threaded
Jobs system. It's non-blocking and your domain object will show the simulated
fluid as it becomes available for that frame.
A nice extra thing for the future would be to improve the visualisation of the
object's state while baking, and also the jobs system/ui could do with some
touchups - currently it has to share a bit from the 'render' job, and appears as
'Render' in the header. Progress bars for jobs in the header would be great too.
* Added 'id_name' property, which is used as the "typeinfo_name" by Keying Set instances. This is simply the name of the relevant KeyingSetInfo classes.
* Renamed the 'array_index' arg for ks.add_path() to 'index'. Also removed the 'entire array' toggle arg in favour of just passing -1 to index. However, Keying Sets in general still maintain their 'entire array' toggle flags for now, it's just that the API function does conversion between the two.
C functions and python used different argument order, this relied on mapping non-keyword arguments to 'REQUIRED' arguments but meant that you could not have an optional, non-keyword argument.
next commit will make order of arguments consistant (currently only changed order that rna wrapped).
