Is there a way to access the new globals.delta_time from a compute shader or do I need to create my own bind group?

For example if I want to use globals.delta_time in the game of life example I need to import #import bevy_pbr::mesh_view_bindings But it hasn't been bound.

@sonic schooner might know the answer to this, as they did the work to get delta_time in globals

I'm not super familiar with the compute shader pipeline, but yeah I'm pretty sure you'll need to create your own bindgroup

Not sure if uniforms would work through AsBindGroup derive. But for storage buffers currently a separate impl AsBindGroup is needed. I did a pull req a few days ago, you can check the code for pointers: https://github.com/bevyengine/bevy/pull/6669/files
