Drawing can use two types of font:

• TrueType font - is created and controlled completely by the Drawing. The user has not to worry about these fonts. He (she) should only tell the typeface and weight. In other hand, he (she) can't change the glyphs of such font.
• Vector font - is empty just after it has been created by the Drawing. The user must set the size (number of glyphs) of the vector font and fill the Vertex Container of every glyph. The sample is the CAD font described in the .shx files. The CAD filter creates vector fonts contained in the .shx files. The user has the complete controlling and responsibility for such fonts.
