Resize an object.

#params

newsize: The new x, y, and z dimensions.

auto: When true zero’s in newsize will scale the proportionaltely to the given axis. Auto can be a vector of three bools to exclude an axis from the auto.

convexity: The number of outside edges a ray might encounter when passing through the object.

children: A list of Scad objects separated and ending with a semicolon.

expansion: A Scad struct literal.
