* The Text-Renderer subsystem provides a simple way to draw text into a
* framebuffer. The system is modular and several different backends are
* available that can be used.
- * The system is split into:
- * - Font renderer: The font renderer allows selecting fonts and rendering
- * single glyphs into memory-buffers
- * - Text renderer: The text renderer uses the font renderer to draw a whole
- * console into a framebuffer.
