Saves the current graphical state of the PDF document. This includes graphics parameters such as clipping path, coordinate system, current point, dash pattern, flatness, line cap style, line join style, line width, miter limit and color parameters like fill and stroke colors. In addition, some PDF parameters are saved including character spacving, word spacing, horizontal scaling, leading, font, fontsize, text rendering and text rise.

In the example below, try commenting out the lines calling pdf_save() and pdf_restore() to measure the effect of saving and restoring the environment.
