This method is called when the user starts interactively resizing a snip (the one that is selected; see find-next-selected-snip). If #f is returned, the interactive resize is disallowed.
See also after-interactive-resize, after-interactive-resize, and interactive-adjust-resize.
The snip argument is the snip that will be resized. This method returns #t.
