Arguments: grid-object
Returns the color, if one has been specified, in which to draw a
border along the right side of a grid-column or grid-column-section, or along the
bottom of a grid-row or grid-row-section, or around an
entire grid-widget. The setf of this function may be called
to change the color, at which time the grid will be drawn as needed to
display the new color.
The value may be either an RGB color object (as returned by make-rgb or ask-user-for-color), or a
symbol whose global value is an RGB object, or nil. The initial value is nil. When nil, effective-border-color
will find a color to use in some other way.
An exception to the above rule is that if the object is a grid-widget then nil is
not a valid value, the initial value is the value returned by system-edge-shadow-color,
and effective-border-color is not
called.
