Saves Scad objects to a file in a separate thread.

Allows setting global $fa, $fs, or $fn. $fn overrides $fa and $fs so cannot be specified with $fa or $fs.

#params

stack_size: The size of the stack in megabytes.

path: The path of the file to save.

fa: The minimum angle between segments or faces.

fs: The minimum length of a segment or face.

fn: The number of segments or faces in a circle.

children: A list of one or more Scad objects separated and terminated with a semicolon.
