  - Camera remains usable while dialog is active.
  - Preview has 3 modes: Auto, Delayed, and Manual.
  - Many existing dialogs have been updated to support
    the new changes.(Shapes, Drag Args, Absolute Cmds,
    Numeric Camera, and Selection tools).
  - Revised N-Cube and placed it at top of Shapes menu
    and removed Cube menu entry.
  - Values for Sliders and Text Entry Boxes with numeric
    data can be increasd/decreased with the Scroll wheel.
  - Constraints [Shift, Ctrl, Alt] work when changing
    values using the scroll wheel within dialogs.
