An alternative to the Alt+Shift+Drag functionality of the LM Transform Layer tool. Allows you to precisely enter the Z value by typing in the number.
This tool is useful for creating parallax effects. It activates when the current frame is positive.
This script was created long time ago in 2013, before the Alt+Shift+Drag functionality of the LM Transform Layer was introduced. However, it's still useful because it allows you to type in the Z value precisely.
