Upstream changes from the prior version of the port include:
- New fractal types including the Spidron hornflake, Sierpinski, Koch
and many others from the fractint formula database.
- New tutorial movies, new examples.
- Improved fonts for large screen sizes.
- Improvements to translations, a romanian translation, and many
bugfixes.
- Build knobs for the port have been trimmed to ease port maintenance.
The one remaining knob, "PTHREADS", switches on experimental
support for multi-cpu machines.
- The port now adopts the system default for CFLAGS and does not
hardcode compiler switches for aggressive optimization.
