Scrollable
to match the width of the viewport.
For example a normal
text view that supported line wrapping would return true here, since it
would be undesirable for wrapped lines to disappear beyond the right
edge of the viewport. Note that returning true for a Scrollable
whose ancestor is a JScrollPane effectively disables horizontal
scrolling.
Scrolling containers, like JViewport, will use this method each time they are validated.
