Description

The argument region must be either a bounded region (such as a line or an ellipse) or some other object that obeys the bounding box protocol, such as a sheet.

This function often returns an existing object, so you should not modify the returned result.

If into is supplied, it is a bounding box that might be destructively modified to contain the result.
