//! This example shows how to render `Change`s directly to
//! an instance of `Terminal`.  When used in this way, the
//! library performas no optimization on the change stream.
//! Consider using the `Surface` struct to enable optimization;
//! the `buffered_terminal.rs` example demonstrates a simple
//! way to enable optimizations.
