The default was changed with an initial implementation of the feature.
With the feedback from animators, having a behavior which affects curves
outside of a changing range is not convenient for professional animators
working on high quality character animation. On the other hand, automatic
smoothing is better for casual animation of object motion.
This change adds an ability to change the default via User Preferences.

Currently unused, but will allow to keep of an owner of the depsgraph.
Could also simplify other APIs in the future by avoiding to pass bmain
explicitly to relation update functions and things like that.
This partially reverts commit 0b2d1badec
Post increment can deep-copy for C++ iterators, while in my own checks
GCC was able to optimize this to get the same output,
better follow C++ best practice and use pre-increment for iterators.
Some external tools seem to have issues with the definition
of Collada <transparency> - a float value in range (0,1).
However it is possible to use the <transparent> color as a container
for the <transparency> value. This seems to be a more reliable
method to export transparency values from Blender PBSDF Shaders.
The relevant documentation is in the collada 1.14 reference manual,
page 7-5 about the usage of transparent and transparency.
This fix makes export and import of the <transparency>
and <transparent> values more convenient and more reliable.

Fixed: The Collada Exporter only supports export of
Lambert Shaders. But Shininess is not supported with
Lambert Shaders. The exporter must not add Shininess
to the Shader data!
Fixed: The Collada Importer adds an illegal value of -1
for reflectivity when this parameters is not defined in
the imported collada data. Now reflectivity is only
set when the import data contains a valid value.
Discarded: The Collada Importer handles shininess in a
dubious way. I have discarded import for now.
This needs to be reworked carefully in 2.81.

- added import of transparency and emission into principled BSDF Shader
- added support for importing all default collada material parameters
* diffuse
* emission
* index_of_refraction
* shininess (mapped to BSDF Roughness)
* reflectivity (mapped to BSDF Metallic)
* transparency + transparent mapped to BSDF Alpha)
* ambient (creates unconnected texture node)
* specular (creates unconnected texture node)
* reflective(creates unconnected texture node)
- added support for exporting collada material parameters:
* diffuse
* emission
* index_of_refraction
* shininess (mapped to BSDF Roughness)
* reflectivity (mapped to BSDF Metallic)
* transparency + transparent mapped to BSDF Alpha)
- prepared support for exporting the following parameters
but currently commented out:
* ambient (creates unconnected texture node)
* specular (creates unconnected texture node)
* reflective(creates unconnected texture node)
Problem: For now we only allow export of principled BSDF based
materials. I am not sure from where to get ambient, specular
and reflective as those values are not included in the
principled BSDF Shader (wip).
1.) The Blender order of applying transforms is:
Scale
Rotation
Transformation
Reasoning: This order ensures there is no shearing, which happens
when you do scaling after rotation, see also:
https://blender.stackexchange.com/questions/1806
The Collada exporter now exports in the order how the transforms
need to be applied upon import.
2.) Also removed obsolete #if 0 lines
Currently we can not export Decompsed Transforms in combination with
Armature asnimations. As a temporary workaround enforce export
of transformations as Matrix for armature objects.
