// - RF_USEAXIS, addentities, predraw,
// - CL_GetEntityMatrix (in engine but is called from other functions so transitively any of them can use the globals - e.g. V_CalcRefdef, maybe others)
// - however RF_USEAXIS is only used if MF_ROTATE is used which is only set in one place
-// - e.camera_transform / CL_VM_TransformView (in engine)
+// - e.camera_transform / CL_VM_TransformView (in engine
+// - this is the only used function that both sets and gets the globals (aim does too but isn't used in our code)
