Feature request: CLI viewer with control of camera angle/position and render to file

[sleeplessTLV]

Hi,
I use Brush for GS creation, and love the light app and CLI. Since it already does all the hard work, I would have loved for it to have a CLI option (or TCP or HTTP POST) to control camera attitude of the GS and render to file, so one could programmatically from 'outside' Brush create animations of the GS or even just single shots. Any chance this will happen?

Per #168 - Ortho would be nice (a super low FOV camera likely would do for now), and maybe the UI could have some of these options too.
