+ * The following hack is made so that we can reuse the definition
+ * the cairo definition of cairo_path_t without having to translate
+ * between our own version of a bezier description and cairos version.
+ *
+ * to avoid having to include <cairo/cairo.h> in each and every file
+ * including this file we only use the "real" definition when cairo.h
+ * already has been included and use something else.
+ *
+ * Note that if you really want to work with GimpBezierDesc (except just
+ * passing pointers to it around) you also need to include <cairo/cairo.h>.
