* NoteCharacter knows how to draw a character from a font. It may be
|

* optimised for screen (using TQPixmap underneath to produce
|
|
* 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.
