Revision bdb341bc

Added by Leszek Koltunski about 8 years ago

Dynamics: Introduce 2 Modes of operation:

- 'random access' mode, where we are able to call a single Dynamic from multiple thread simultaneously.
- 'sequential' mode, which only permits sequential interpolation from one client.

The second mode has an advantage when one needs to change mDuration: it keeps on interpolating smoothly. In the first mode, this is not possible.
