[REQUEST] JMPBody option to update marker locations when scaling body

[SpencerTWilliams]

Is your feature request related to a problem? Please describe.
Currently, markers are left in their previous positions when bodies are scaled in JMP. For some uses, however, we would want the markers to be able to move as the body scales to preserve their locations relative to anatomical landmarks.

Describe the solution you'd like
There should be a true/false option with a name like <update_marker_positions_with_scaling> in that can be added to any <JMPBody>. If it is set to true, markers on the body should be allowed to move when the body is scaled, instead of being moved back to their original unscaled positions after scaling geometry.

Describe alternatives you've considered
Without this option, solving certain problems requires manually changing the code.
