+ * low-resolution colour or greyscale glyphs) or printer (using some
+ * internal representation to draw in high-resolution monochrome on a
+ * print device). You can use screen characters on a printer and vice
+ * versa, but the performance and quality might not be as good.
+ *
+ * NoteCharacter objects are always constructed by the NoteFont, never
