change shadow resolution without restart

[Gibbz]

Godot version:
3.1

OS/device including version:
rx580

Issue description:
Im working on a project where we are currently incorporation some graphics options. It would be nice to be able to apply the settings without needing the user to quit and relaunch the game. We have this issue mainly with shadow resolution.

Ive had a further look into the viewports. It would be great to get the following settings added to the viewports so the user doesnt need a restart:

• target frame rate/frame cap
• shadow sizes (directional especially)
• anisotropic filter level

• target frame rate/frame cap

Just set Engine.target_fps at any time 🙂

Nice, that may be helpful!
It would be nice to have independent frame rates for render viewports for performance and style purposes :)

To render specific viewports at a lower frequency, you could render them manually by setting their Update Mode to Once repeatedly using a timer.

I'll close this issue in favor of #18621. If you still need it, please open another issue related to changing the anisotropic filtering level at runtime 🙂
