The text area is inside a ScrollPane (line 30), which provides scrolling functions for the
text area.
The wrapText property is set to true (line 26) so that the line is automatically wrapped
when the text cannot fit in one line. The text area is set as noneditable (line 27), so you cannot
edit the description in the text area.
It is not necessary to define a separate class for DescriptionPane in this example. How-
ever, this class was defined for reuse in the next section, where you will use it to display a
description pane for various images.
