Construct a callback-backed target in one line for host/runtime integrations.

Examples

use ailloli_ui_openxr::{build_callback_source, OpenXrHostResult, OpenXrImageFrame};
use ailloli_ui_render::render_target::PhysicalExtent;

    wgpu::TextureFormat::Bgra8Unorm,
    || -> OpenXrHostResult<OpenXrImageFrame<u64>> { panic!("host acquires") },
