illusion of extra dimension(s)

[cKleinhuis]

i just want to note, that 3d images are not always bound to a special file format,
especially iterated function systems can never really be saved as a surface, because
they would ideally converge against an surface, but this surface can never be described
as smooth surface .... so, i think it leaves to me to decide which images can enter
the 3d section ... by now i have let the decision to the user if the user thinks
the image can compete in the 3d section, i let him ....

the idea with 3d and 2d section is that 3d programms let you enter properties
that make no sense in pure 2d images, this is why i told margit to treat her
beveled images as 3d because they feature a "light" source...

i hope it gets a bit clearer ....
