11// This file has been written using FSD_File.hxx as template.
12// This is a specific adaptation for Draw use (save & restore commands).
13// It is not sure at all this code is portable on any other plateform than
14// SUN OS. Don't use it anywhere else.
15// Thanks for comprehension. (22 august 97)
