It depends on the platform. On RealityEngine, you don't block
until the RGBColor. On Extreme, Elan and friends, you block on the
swapbuffers. On the current version of software for IMPACT, you
block on swapbuffers, but this might (and hopefully will) change,
since it can be useful to do processing after swapbuffers on
single processor machines.
