Function clear_to_background 

pub fn clear_to_background(
    device: &Device,
    queue: &Queue,
    view: &TextureView,
    color: Color,
)

Clears view to color and submits the work, through the same WgpuFrameGraph every other command encoder and submission in this crate is required to go through (enforced by render_contract.rs’s wgpu_command_buffers_are_owned_by_frame_graph_executor) — a fresh, one-shot WgpuFrameGraphExecutor, since a placeholder clear has no frame-to-frame state worth pooling. Does not present or acquire anything itself — callers that mean to show the clear on screen still acquire a frame and call wgpu::SurfaceTexture::present themselves, exactly as a real content frame would.
