TODO:

A proper ascii chart for each font would be nice as well. May need 
a full page per font for this. Fonts with more than 255 values could present
a formatting problem.

Create optional sample paragraphs block.

Make a PDF sample page for the web site using three example fonts such as...
Utopia, Bitstream Charter  Luxi, Helvetica or any of the Web fonts 
 - Trebuchet, Times *New * Roman, Georgia

You can manually hack the code to produce less sample lines per font, 
then more fonts may fit on the page. The status bar currently does not
reflect this. It will assume three fonts per sheet. Later we may add a
user dialog to select the sample lines to be printed.

Need improvments to the clean up code to insure that temp images are removed 
from .scribus folder.

Improve the Listbox events coding.

Continual holding of Up or Down keys causes preview to be redrawn rapidly. This causes
a number of problems.  Needs a timer to delay redraws when scrolling.

Improve on the documentation of the functions.
