the render layers: they are broken

[brandon-reinhart]

Bevy version

0.15

What you did

1. I rendered a bird into RenderLayers 0 and another into RenderLayers 0 and 1.
2. Camera A has RenderLayers 0
3. Camera B has RenderLayers 1 and a RenderTarget Image.

What went wrong

We expect to see both birds on Camera A and only one bird on Camera B, which is drawn as an ImageNode to display the RenderTarget contents.

Instead we see... a random combination of birds on both cameras. ?!?

Example code is here: https://github.com/dead-money/bevy_render_layers_broken

Every few seconds the example despawns everything and recreates the scene. You'll see arbitrary results.

@tychedelia Any ideas? This looks like your area.

Yeah, happy to look into this later this week. Thanks for providing a repro @brandon-reinhart.
