I had to add some ugly RNA path finding code here, checking for all places these structs can possibly be reused. Can't think of a better way to go about this though with the path stored in the RNA type...?
It will still flip, but it now has a small buffer region before it does that which returns a really large positive or negative value. This still only happens in perspective cases, when moving along an axis that is nearly aligned with the view.
- revert tiff load/save to use standard libtiff (to ensure 100% colorimetry & alpha interpretation across platforms)
- include patch #18720 to fix load of libtiff dynlib (if present on system)
- added scene.bases (like scene.objects)
- renamed group create operator.
Example
scene = bpy.data.scenes[0]
C = {}
C["scene"] = scene
C["selected_editable_bases"] = [scene.bases[2], scene.bases[3]]
bpy.ops.group.create(C)
Also made operator fake modules not return __call__ (reported by Stani, fixes autocomp. bug)
1) "Even Divisions" - This option ignores the length of bones when considering how they should fit along the curve. This is useful for getting a smoother curve fit without having to worry about getting the bone lengths spot on. By default, this is disabled.
2) "Keep Max Length" - This option prevents the bone chain from extending past its natural length when the spline is stretched beyond that length. When the spline length is substatially shorter though, this bones get scaled to zero; making this option possibly useful for doing "growing tips".
This is essentially a 'no scale' option, although the behaviour when the curve is shorter is really a compromise since the curve cannot be accurately satisfied + left intact without some scaling being applied due to the way this works.
3) "Radius to Thickness" - The average radius of the spline between at the head+tail of each bone determines the x+z scaling of the bone.
note that you can still set rna properties like this.
bpy.data.__dict__["var"] = 1
print(bpy.data.var)
but this is only stored for the python objects lifetime and not actually attached to blenders data
* Fixed crash when reloading a file with Spline IK and/or Damped Track constraints. The targets for these constraints weren't getting relinked.
* Fixed problems with removing Spline IK making some bones unable to be manipulated.
* Jotted down some comments in the Spline IK code noting places where additional tweaks will be added.
For now, this just assumes that the 'lens' parameter was animated (assuming a perspective lens was used). Unfortunately, this may not always be correct, but at least there's a path now that can lead to further tweaking.
At last, this commit introduces the Spline IK Constraint to Blender. Spline IK is a constraint that makes n bones follow the shape of a specified curve.
Simply add a chain of bones, add a curve, add a Spline IK Constraint to the tip bone and set the number of bones in the chain to make it work. Or, try the following test file:

I've implemented this in a similar way to how standard IK solvers are done. However, this code is currently not an IK plugin, since I imagine that it would be useful to be able to combine the 2 types of IK. This can be easily changed though :)
Finally, a few notes on what to expect still:
* Constraint blending currently doesn't affect this. Getting that to work correctly will take a bit more work still.
* Options for not affecting the root joint (to make it easier to attach the chain to a stump or whatever), and non-uniform scaling options have yet to be added. I've marked the places where they can be added though
* Control over the twisting of the chain still needs investigation.
Have fun!
Reordering some function calls in transform cleanup to make it simpler (that means other fixes are possible too, sequencer probably don't need it's own freeing function anymore).
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.
