Geometry Node: 'Active Camera' (Category: Input)

An 'Input' category node that always provides info about the current active camera.

Effectively operates in an identical fashion to the Object Info node, only it doesn't ask for an object input to return information, it only ever provides information about the current active camera.

Bonus implementation points, include outputs such as:

• Camera FOV
• Camera Frustrum shape as 'Geometry' to use for boolean operations and other fun uses.
• Camera DoF focal distance
• Camera Clip Start/End

Example Use Cases:

• Automatic LOD Systems
• Billboard Rendering
• Vfx (eg: dust in front of cameras)
