+% This is an "unobsfucated version of postscript header" in printerjob.cxx. It
+% was probably kept separate for the comments, but it is not used in it self
+% and probably was not kept in sync with the actual header.

+%
+% readpath
+%
+% The intention of readpath is to save disk space since the vcl clip region routines 
+% produce a huge amount of lineto/moveto commands
+%
+% The principal idea is to maintain the current point on stack and to provide only deltas
+% in the command. These deltas are added to the current point. The new point is used for
+% the lineto and moveto command and saved on stack for the next command.
+%
+% pathdict implements binary/hex representation of lineto and moveto commands. 
+% The command consists of a 1byte opcode to switch between lineto and moveto and the size
+% of the following delta-x and delta-y values. The opcode is read with /rcmd, the two 
+% coordinates are read with /rhex. The whole command is executed with /xcmd
