Objective

• bevy_framepace has been used in production by many bevy users for a few years. It's a useful feature that could benefit from a more complete integration in the engine.

Solution

• Upstream the crate almost as-is with some very minor changes.
  • The monitor refresh rate is now read from bevy_window instead of bevy_winit so this will work with any window backend.
• The crate now lives as a module inside bevy_render

Testing

• I tested the new example and it behaves like the one from the original crate

Notes

There are various improvements that could be done to this crate, but I believe this should be done as follow up PRs.

This is fun (especially the sleeeep part, love it!) :D , I think a table would be a better way to format this information.

That was copied from the original crate. I'd prefer keeping changes to a minimum in this PR.
