The latest patch to Fractint/Xfractint is now available at www.fractint.org. There are no diff files because I restructured the source to make it easier to maintain. I did provide source trees. What new: Added the mathtolerance and orbit_delay parameters to values written to PARs and GIFs. Fixed how a mathtolerance parameter with a slash and a second number, but no first number is read in. The slash was being interpreted as a double. Stole the <p> key for use by passes options. If you are brave enough to try it, printing is still available using <ctl-p>. Put periodicity and orbit delay on the new <p> screen. There are currently two drawing modes available for the passes=orbits option. The rect(angle) method plots the orbits in a rectangle that can be zoomed, rotated, and skewed using the <F6> corner parameter screen, and the straight line method plots the orbits between two points specified on the <F6> corner parameter screen. The orbit interval parameter plots every nth orbit. The maintain screen coordinates parameter lets you zoom into an image changing the coordinates of the line or rectangle used to generate the image, but keeps the display coordinates, set on the <F2> screen, the same. Updated the docs for center-mag and corners because center-mag is now the default. Restructured the source to make it easier to maintain. Jonathan
