//!
//! let dejavu = FontRef::try_from_slice(include_bytes!("../../fonts/DejaVuSans.ttf"))?;

//! // Simple font mapping: FontId(0) -> deja vu sans, FontId(1) -> garamond
//! let fonts = &[dejavu, garamond];
//!
//! // Layout "hello glyph_brush_layout" on an unbounded line with the second
//! // word suitably bigger, greener and serif-ier.
