tried to copy list item after previously disposing of a list control. Lists
include gradients, textures, and controllers.
- Terminate Show Orbit if the orbit point falls
far outside image. Before this change, application could hang if you used
Show Orbit when zoomed way in.
- Remove Orbits property from orbital fractal
properties page. This was overly complex and unnecessary since you can use
Max Count to increase the number of orbit points.

Initial Z in orbital equation. The need for
Zinit Range was related to obsolete
Orbits property.
- Minor updates to simplify several built-in Orbital Equations.

associated with an array of affine transformations for the purpose of
generating an IFS fractal from the transformations.
- Added method Affine.ScaleDimension to
built-in macros. This method can be used to sharpen/blur an IFS fractal
without changing its general shape.
- Added an option to control the method used to generate weights in Orbital
Equations:
- IFS Examples - Chaos and Fractals
- IFS Examples - Yale
- IFS (Search)
- Added an option to sharpen/blur the IFS in the Orbital Equation
IFS File Processor.
- Added logic to adjust the Orbital fractal's Max
Count based on window size. This reduces the need to adjust
Max Count manually when you change the size of
the window and improves the performance of the Preview window with respect to
Orbital fractals.
- Added a color adjustment option to several strange attractors.
- Added several examples to Orbital Equation Symmetric
Icon - Variations.
