The Xerxes example is using an `ImmModeSink` It's essentially emulating immediate mode, but buffers the data from all of the fixed commands, and sends a modern set of data buffers + shader to the actual GPU.

Might wish to try printing out the results of `glAvailabilityToString()` just to see what JOGL thinks it's working with.
