Add support for change in number of particles in displacement modifier
I'm working on a simulation with increasing number of atoms (gas phase) and these particles will over time attach to a surface so they can grow crystals. I then want to use the displacement modifier to study what the existing atoms do (jump diffusion etc). Currently, Ovito doesn't like that a particle with identifier k exists at frame n, but not at the reference frame.
Would it be possible to add support for this situation? It could for instance give 0 displacement, or ignore particles, for particles that didn't exist at the reference frame.
