Way to disable renderer for specific window.

[entropylost]

I want to use a different renderer for my game instead of bevy, but still have other debug windows using the bevy renderer.

As such, I'd like there to be a convenient way to prevent bevy_render from running present or doing anything with one of the windows created by bevy_winit (as because of the structure of winit, it'd be somewhat difficult to manually spawn a separate window and have its event loop work with the bevy ecs). Without this, I have a lot of frame flickering since my swapchain ends up conflicting.

I have also been able to do this by running commands.entity(window_entity).remove_component::<RawHandleWrapper>(), but this is dependent on internals.

Alternatively, I suppose I could figure out how to do interop between the graphics apis and bind it to a wgpu texture, but that seems complicated.
