TextShapingDriver

Interface for implementing text shaping logic.

A TextShapingDriver is responsible for converting a string of characters into a visually accurate sequence of shaped glyphs, accounting for font-specific details, writing direction, and script characteristics. This process is pivotal in rendering text in a way that adheres to the typographic and linguistic rules of the specified script and language system.
