Network rendering - frame distribution across slaves

[DriesV]

Currently KeyShot network rendering works by splitting up frames and distributing 'render buckets' across all connected slaves.
For most cases (like, +95%) this works great. However, for that other 5% it is not ideal.
E.g. scenes with complex caustics can take longer to render on the network vs. on a single machine. Probably because of how the photon map needs to be recalculated for each slave?

For animations with caustics, network rendering would be much faster if whole frames were distributed across slaves. A single frame would be rendered by just one slave. This would get rid of the recalculation caused by caustics.
