Unclear why neck_zoomin camera is treated differently from, eg. head or tarsus cameras
Checking if the camera is a camera defined in the XML (I think this is what it does?) by checking if the name contains "Animat" is a bad idea — in multi-fly simulations, cameras attached to different flies might have names that start with different strings because the flies might have different names.
Why does the camera have to be attached to a fly? Shouldn't this be optional in case of static cameras attached to the arena?
See #185, #187.
