* Viscoelastic springs between the fluid particles can simulate all kinds
of viscous and elastic substances, such as jelly and honey. This is
achieved by creating springs dynamically between neighboring particles
and adjusting their rest length based on stretching/compression.
* This nearly completes the currently intended functionality for particle
fluids. The last missing thing is a surfacing extraction algorithm,
which is needed for a proper representation of a sph fluid.
* I also cleaned up and renamed some of the fluid parameters to make the
ui a bit easier to understand.
* One addition to the patch is an option to use "initial rest length" for
the springs, which uses the lengths between the particles at the time of
spring creation as the spring rest lengths instead of interaction radius/2.
This makes the fluid keep it's original shape better (good for very
viscoelastic materials), but can create large density differences inside
the fluid (not really physically correct for a fluid).
* Viscoelastic springs are stored in point cache as extra data.
* Not strictly necessary right now, but better for future.
* Struct data (only boids at the moment) is now written as structs (with dna) so they work between 64 and 32 bit machines too.
* I've getting bad feelings about the point cache index_array for a while (cause for this bug too), so from now on memory cache uses a simple binary search directly on the index data to handle queries to specific data points.
* This is a bit slower than just checking from a dedicated array, but it's much less error prone, uses less memory and makes the code more readable too, so it's not a tough choice.
This allows manual (point by point) animation of their control verts,
although many other settings cannot really be animated with any
visible effects yet. Interestingly, lattices also had IPO block
pointers, though they were never really used (AFAIK).
Todo:
- Animation Editor support has yet to be added. I've got a few other
things to add to, so will group those changes together.
- skip fixing file paths on undo.
- simplify bpath alloc and free functions, also pass Main structure so as not to rely on G.main, (needed for file load).
The Freestyle tab in the Render buttons has a couple of new
options "Group" and "Group Negation". The Group option specifies
a group of objects (defined through the Groups tab in the Object
buttons), while the Group Negation value is either INCLUSIVE or
EXCLUSIVE. If INCLUSIVE, feature edges belonging to some object
in the group are selected. Otherwise, those feature edges not
belonging to any object in the group are selected.
- use sizeof() in more places.
- fixed some off by 1 bugs copying strings. setting curve font family for instance was 1 char too short.
- replace strncpy and strcpy with BLI_strncpy
Both stored the filename of the blend file, but G.sce stored the last opened file.
This will make blender act differently in some cases since a relative path to the last opened file will no longer resolve (which is correct IMHO since that file isnt open and the path might not even be valid anymore).
Tested linking with durian files and rendering to relative paths when no files is loaded however we may need to have some operators give an error if they are used on the default startup.blend.
- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi
Most stylization parameters in line style datablocks are now
animatable by means of keyframes. Right click on a line
style parameter, and you will see a list of keyframe-related
commands in the context menu.
Concerning the implementation, RNA path resolution has been
extended to properly address color ramps in line style color
modifiers. File I/O has been also improved to load/save the
animation data associated with line style datablocks.
Known issue: Freestyle-related options in render layers are
not animatable at the moment, because of general inability (or
maybe a bug) that keyframes cannot be inserted with respect to
render layer options.

...also applied a fix so this flag wont be written but including this patch for older startup.blend's.
--- from the tracker
I've created a patch for the texture path corruption bug, 23337. Basically, G_FILE_RELATIVE_REMAP was improperly getting
saved out to the startup.blend file, causing issues when the autosave timer went off. The proper fix is to mask out
that flag so it doesn't get written out to .blend files itself, but since that doesn't fix any pre-existing startup.blend
files, I just mask it out when startup.blend is read in instead.
I've tested it locally and so far, it seems to fix all the issues I've had with texture image paths getting corrupted.
I haven't figured out how to properly test the remap-on-save option in the save as dialog, though, so I don't know if
I accidentally broke that or not (although I don't see how I could have).
- remove brush array for each Paint struct, just use a single brush pointer.
- removed rna function based template filtering.
- filter brushes using a flag on the brush and the pointer poll function.
- set the brushes using a new operator WM_OT_context_set_id().
TODO
- remake startup.blend, currently brush groupings are lost.
- rewrite WM_OT_context_set_id() to use rna introspection.
* Animation data for meshes wasn't getting saved at all (the linked actions were, but that doesn't really count)
* Lib-linked actions from other files may not load correctly too
A number of UI elements were newly introduced to control line color, alpha
transparency and line thickness by means of base color/alpha/thickness plus
modifiers that alter the base values. To begin with, three basic modifiers
were prototyped with the aim of putting the new UI framework in practice
and evaluating if it works properly.
The Parameter Editor mode is still in a work-in-progress state and totally
useless from users' viewpoint.
