Draws a single character to the display buffer in the current pen colour. The `c` parameter should be the ASCII numerical representation of the character to be printed, `x` and `y` describe the top-left corner of the character's drawing field. The `character` function can also be given an optional 4th parameter, `scale`, describing the scale of the character to be drawn. Default value is 2.
