The generic function pane-adjusted-offset
calculates the offset required by adjust so that the pane pane of size actual-size pixels is placed correctly within available-size pixels in its parent layout. It is called by all of the layouts that inherit from x-y-adjustable-layout to interpret the values of x-adjust and y-adjust.
Typically, adjust will be a keyword or a list of the form (keyword n)
where n is an integer. These values of adjust are interpreted as by pane-adjusted-position.
However, new methods can accept alternative values for adjust where required and can also add extra keywords. For example, grid-layout allows adjust to be a list of adjust values, and then passes the offset into this list as an additional keyword.
