From Wang Rui, "Attached are two simple modifications of osg::Sequence and

osg::Texture1D classes, for the reason of implementing the I/O
serialization feature. In the Sequence header, I've added some more
convenient functions: setTimeList/getTimeList,
setLoopMode/getLoopMode, setBegin/getBegin, setEnd/getEnd,
setSpeed/getSpeed and setNumRepeats/getNumRepeats.

In the Texture1D header, fixed:

inline void setTextureWidth(int width) const ...

to:

inline void setTextureWidth(int width) ..."

Notes from Robert Osfield, have gone a little further with these changes and have removed some of the original get methods that were out of step with the way the rest of the OSG manages the set/get property pairs.
