 * Font resources:

 * Configure font resources and search for fonts

 *

 * In the easiest case, load a host font on Windows or Mac which is already

 * installed in the system. Then, use the "SearchPath" resource category to

 * define the folders for your fonts to be found. In the next case, use a font

 * where the font file name equals the font name. If the font name and font

 * file name are not equal, use the "FontOutline" resource category to define

 * a font name to be used by PDFlib. For Type 1 fonts, use the "FontOutline"

 * and the "FontAFM" (or "FontPFM") resource categories to define a font name

 * to be used in PDFlib. With info_font() get the font name and the font file

 * name.

 *

 * Required software: PDFlib Lite/PDFlib/PDFlib+PDI/PPS 7

 * Required data: font file
