Finally, I have fixed TemplateTarget<osg::Quat>::lerp() as it was giving incorrect results when interpolating between some small rotations.
From Cedric Pinson, i renamed the method in channel to be more general. Adjusted the CubicBezier key constructor to use a single value as input.
Update Timeline.cpp to add current layer to the ActionVisitor, use correctly the priority
Add accessors in Action.cpp to retrieve protected data
Split files and rename them to classname
Change de default color of UpdateMaterial to FFOOFF to detect unset value
Add accessors in LinkVisitor instead of accessing data directly
Update osganimationtimeline example to fit the api callback
- Animations with equal priority are now weighted correctly relative to each other
- (minor) Channels no longer store their weight as the only time it's used is in update() when Animation can pass in the weight directly
From Cedric Pinson,
- I adjusted the quaternion blending to keep the commutativy property
osg::Animation::TemplateStepInterpolator::getValue the code tries to return
the result rather than assigning it to the result parameter reference.
The following patch fixes this."
Note from Robert Osfield, I've temporarily re-enabled the old focing of of color and depth attachment to avoid regressions on some OpenGL driver. We'll revist this once
we have a mechanism for controlling this override at runtime.

i.e.

behind osgText::Text. I made it so the box would get drawn using
whichever BackdropImplementation was selected. However, I did not
implement STENCIL_BUFFER. In that case it defaults to drawing the
bounding box using POLYGON_OFFSET instead.
Also made it so the BOUNDINGBOX and FILLEDBOUNDINGBOX are drawn with a
settable color and margin size.
While I was at it I tightened up the values applied with DEPTH_RANGE
and POLYGON_OFFSET, not just for drawing the bounding box but also for
drawing backdrop text (these values must be coupled since the bounding
box has to be drawn deeper in Z than the backdrop text). The values
in use before seemed like overkill and I was seeing some z-clipping
with my background scenery in the case of DEPTH_RANGE. If there was a
good reason for the large values please let me know...."

Selection is now just a typedef of osg::MatrixTransform, and is deprecated
CommandManager is shell class that just sets values directly on Dragger, and is deprecated
Dragger now has list of DraggerCallback that takes over the roll of tracking changes to the Dragger, and
allows users to track the dragger in any way they wish.
Dragger now has a convinience method making MatrixTransforms track a dragger.
Selection and CommandManager are no longer required for use of osgManipulator and are kept around for backwards compatibility.
dependent on the complexity of the geometry. For complex scenes this
meant that it looked like you were "throwing" the display into molasses.
For simple geometry things get over-excited once thrown.
The fix is to factor in the frame rendering time to the caluclated
motion. I've implemented this for rotation and panning.
Now when things are thrown they maintain a rate very close to what was
happening when the mouse button was released."
