Description

If I open an NMR ensemble and apply some transform to the group:

open 1pmx
turn 1,0,1 45 models #1

then...

select #1.1
ui mousemode rightMode "rotate selected models"

(or "translate selected models")

... then the rotations and translations are in the model's coordinate frame rather than scene coordinates. FitMap also seems to get confused.

Summary: Non-identity transforms in parent models confuse some algorithms → Move selected models uses wrong coordinates if parent model moved in scene

Fixed rotate and translate selected models.

Would need a test case to diagnose fitmap problems with moved parent model. Often ChimeraX code has not been tested with model hierarchies and moved parent models and since Chimera did not have model hierarchy support code ported from it often only works if the parent model has not been moved in the scene. So it is not surprising that these bugs exists.
