PENDIA.......Pen diameter scale factor (default 0.0). This option allows one to simulate a thick pen when text is drawn. Each character is drawn repeatedly, stepping its origin around a small circle representing the pen diameter. For convenience, the diameter value is given as a fraction of the character height, rather than as an absolute number. A value of about 0.01 to 0.03 often gives reasonable results. A value of 0.0 will revert to normal text plotting.
