The SmeBSB object is used to create a menu entry that contains a string,
and optional bitmaps in its left and right margins.  Since each menu
entry is an independent object, the application is able to change the
font, color, height, and other attributes of the menu entries, on an
entry by entry basis.  The format of the string may either be the encoding
of the 8 bit <function>font</function> utilized, or in a multi-byte encoding for use with a
<function>fontSet</function>.

This is a name of a bitmap to display in the left or right margin of the
menu entry.  All 1's in the bitmap will be rendered in the foreground
color, and all 0's will be drawn in the background color of the
SimpleMenu widget.  It is the
programmers' responsibility to make sure that the menu entry is tall
enough, and the appropriate margin wide enough to accept the bitmap.
If care is not taken the bitmap may extend into another menu entry, or
into this entry's label.

This is the amount of vertical padding, expressed as a percentage of
the height of the font, that is to be placed around the label of a
menu entry.. The label and bitmaps are always centered vertically
within the menu.  The default value for this
resource (25) causes the default height to be 125% of the height of the
font.
