[Lightfield viewport] Render "blocks" in viewport #96
Description
Is your feature request related to a problem? Please describe.
Currently, when no LG is connected it is difficult to frame a scene for the LG, since we can only see the center view and don't know how the scene will be looking like from other viewing angles.
Describe the solution you'd like
It would be handy, if the user could select the camera to look through or – even better – to show the scene as a "Block" right within the Blender viewport.
Additional context
The technical realization may be connected to the issue #69.
