Fixed bugs
IFStile features:
-build any affine directed graph iterated function system (IFS) in an Euclidean space of arbitrary dimension (as 2D or 3D section)
-fully automatically find interesting fractal shapes, rep-tiles, multi-tiles, irreptiles, carpets, dragons, etc
-extract the boundary of self-affine tiles as directed graph IFS
-compute dimensions of the boundary of self-affine tiles (numerically and analytically)
-export and import Fractint IFS format, export Apophysis .flame format
-effectively zoom IFS fractals
-render high resolution images (with batch rendering)
-render keyframe animation
-create and save 3D mesh
