<p>The top object is the layout itself. It uses a set of symbols
that resides at the first logical level. Each symbol is uniquely identified
by a seven bit <code>ASCII</code> code. All layout objects share the same set of
symbols. These symbols are used to form text objects on the silkscreen
and copper layers. Undefined symbols are drawn as filled rectangles.
<p>Every font file is preprocessed by a user-defined command when it is loaded.
For details see <code>fontCommand</code>, <a href="Resources.html#Resources">Resources</a>.
