Detailed Description

Bitmap font utilities: CPU-side text rasterization and an OpenGL font engine.

Declares two related components:

• FontRenderer: CPU-only blitter that composes strings into an Image using a bitmap atlas and character box positions read from a text file.
• FontEngine: runtime OpenGL renderer that draws strings as quads using per-character textures; optionally renders from a signed-distance field.
