Depth (3D Space Perspective) [Optional]
Specifing Perspective Depth value, it will create a 3D space of the slide.
For example, the value 50% means the depth is 50% of 3D space size. Given a 3D space with size 400px x 400px, the perspective depth will be (400 + 400) / 2 * 0.5 = 200px.
This option affects appearance of child layers applied with Rotate X or Rotate Y or Translate Z effect.
A 3D space can be created on a slide or a panel layer, it's recommended to create 3D space on a panel layer.
