Font

The Font class provides functionality for loading, managing, and rendering fonts, supporting multiple font styles and sizes. It allows checking if a font is loaded, retrieving glyph advances, and calculating text bounding rectangles for both single and batched text. The class supports creating and drawing text using a specified font style, either character by character or in batches.
