+/**
+ * Adobe PDF Simple fonts implementation
+ *
+ * PDF simple fonts functionality is presented by Adobe Type 1
+ * (including standard PDF Type1 built-in fonts) and TrueType fonts support.
+ *
+ * Both fonts have the following properties:
+ * - Glyphs in the font are selected by single-byte character codes obtained from a
+ *   string that is shown by the text-showing operators. Logically, these codes index
+ *   into a table of 256 glyphs; the mapping from codes to glyphs is called the font’s
+ *   encoding.
+ *   PDF specification provides a possibility to specify any user defined encoding in addition
+ *   to the standard built-in encodings: Standard-Encoding, MacRomanEncoding, WinAnsiEncoding,
+ *   and PDFDocEncoding, but Zend_Pdf simple fonts implementation operates only with
+ *   Windows ANSI encoding (except Symbol and ZapfDingbats built-in fonts).
+ *
+ * - Each glyph has a single set of metrics, including a horizontal displacement or
+ *   width. That is, simple fonts support only horizontal writing mode.
+ *
+ *
+ * The code in this class is common to both types. However, you will only deal
+ * directly with subclasses.
+ *
+ * Font objects should be normally be obtained from the factory methods
+ * {@link Zend_Pdf_Font::fontWithName} and {@link Zend_Pdf_Font::fontWithPath}.
