//! Standard 14 PDF Fonts Metrics
//!
//! This module provides accurate font metrics for the 14 standard PDF fonts
//! as specified in ISO 32000-1:2008 Section 9.6.2.2.
//!
//! These fonts are guaranteed to be available in all PDF readers and don't
//! need to be embedded. The metrics here are based on the official Adobe
//! Font Metrics (AFM) files.
