Module cli 

The example’s command line.

The flags are declared with [argh], which derives the parser and the --help text from the Args struct. A value with a shape of its own — a WxH size — is parsed by the function Args names through from_str_fn, so the rules live next to the option they constrain.

Args::validate holds the checks that span more than one option: here, a scene the example does not know.

The scenes’ snapshots are not compared through this command line. That is a test’s job, and it lives in tests/gpu_suite.rs, where the same bodies run natively and in a browser.
