Use the information provided in the getActiveInstances() in order to
calculate the length of the rocket. This change takes each component
instance and uses the component bounds and the instance's transform
in order to determine the instance's actual bounds. The length is
then calculated as the difference between the min and max X values,
using the BoundingBox.
Note, this particular change special-cases a few of the components
in order to get the right length. It is preferred to revisit each
special case in subsequent patches in order to keep this patch set
minimal for the time being.
The length calculations are already stressed during unit tests, but
the results are a bit more accurate and thus the unit tests are
updated to reflect the new values.
