FontRenderer class
Renders characters to a CanvasTerminal using normal fonts and text drawing. Can draw any character supported by the supplied font. This renderer works best if you keep the scale at 1 and instead adjust the pixel size of the supplied font string based on the device pixel density.

→ Future<
void> -
Returns a Future that resolves whenever the underlying assets used by
the renderer are fully loaded and the renderer is actually ready to
render. Calling renderChar before waiting for this future to resolve may
result in undefined behavior.
