This struct contains the view space coordinates of the near projection plane.
| bottom | Position in view space of the bottom side of the near projection plane. |
| left | Position in view space of the left side of the near projection plane. |
| right | Position in view space of the right side of the near projection plane. |
| top | Position in view space of the top side of the near projection plane. |
| zFar | Z distance from the origin of view space to the far projection plane. |
| zNear | Z distance from the origin of view space to the near projection plane. |
