Arguments: stream position
Returns position after modifying it to be the position to which stream has been scrolled relative to the page top left. This is the destructive version of scroll-position.
An application may override the default method of this and several
other generic functions in order to implement a custom scrolling
scheme that scrolls by logical picture objects rather than by
pixels. See the source code of the Navigator example entitled
'Scrolling by arbitrary objects rather than pixels' for a complete
example." More on this point and a list of the relevant generic
functions can be found on the horizontal-scroll-bar and vertical-scroll-bar
pages.
Note: incompatible change in release 6.0: in releases prior
to 6.0, when a frame-with-single-child instance
was passed to this operator, the operator was actually applied to the
child (the result of applying frame-child to the
frame-with-single-child instance). In release 6.0, this redirection no
longer occurs. If you intend this operator to apply to the
frame-child, pass that to this operator rather than the parent. This
is a non-backward-compatible-change. See the release notes for more
information.
