 *
 * - Updated to cairo version 1.4
 * - Grouped OS specific fuctions in separated units
 * - Organized the functions by group and ordered exactly as the c header
 * - Cleared parameter list syntax according to pascal standard
 *
 * By Luiz Américo Pereira Câmara
 * October 2007
 *
 * - Review of the unit according of cairo.h, cairo-svg.h, 
 *   cairo-pdf.h and cairo-ps.h
 * - Adding structures, enumerations, and methods missing.
 * - Translation and addition of cairo-tee.h, cairo-script.h,
 *   cairo-script-interpreter.h and cairo-gobject.h
 * - Updated to cairo version 1.12
