===Introduction===
The datafiles\fonts folder contains static font definitions such as Commonwealth-10.font. The XML contents of that file specify one particular font, mainly a logical name (Commonwealth-10), a filename (Commonv2c.ttf), and a size (10). To load this static font definition you'd write the following line of code:
<code>
CEGUI::FontManager::getSingleton().createFont("Commonwealth-10.font");
</code>

This works well, but sometimes you need to display a same font in various sizes. One approach is to create multiple .font files, one per font size. But there is a better approach, a way to dynamically create fonts.
