Changing scalar value changes the current point id
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When you change the scalar value of a control point in the transfer function editor, the call to render changes the current id.
This is disorienting to the user who is most likely looking at the line edit, which suddenly changes after they typed. This can be a problem if they were not finished typing and continue to do so on the new current point.
