desktop icon size - pc-bsd

[asdf]

Can anyone tell me how to change the size of desktop icons (pc-bsd 9.0)?
I have searched this forum and also looked at other sources, but I just cannot find the answer.
Is this some sort of a secret or a joke? Was this function removed in order to make this a really LIGHTWEIGHT desktop environment?
