A horizontal panel arranges its subwindows in a single row. See also
panel%.

If the
'border style is specified, the window is created with
a thin border (only in this case, the client size of the panel may be
less than its total size). If
style includes
'deleted, then the panel is created as hidden,
and it does not affect its parent’s geometry; the panel can be made active later by calling
parent’s
add-child method.
For information about the enabled argument, see window<%>. For information about the horiz-margin and vert-margin
arguments, see subarea<%>. For information about the border, spacing, and alignment
arguments, see area-container<%>. For information about the
min-width, min-height, stretchable-width, and
stretchable-height arguments, see area<%>.
Initially returns
#t, but if
set-orientation is called,
this method returns whatever the last value passed to it was.
