Description:

Extracted from Border.
Common superclass for border-painters.
This will replace the mixture of window-system supported borders and manually
drawn 3D levels (which is ugly, but served me well for almost 20years now).

 width: borderWidth

create a new instance of the receiver with a border of the given width
(and default color).

 width: borderWidth color: aColor

create a new instance of the receiver with a border of the given width
and color.

Instance protocol:

 color: aColor

 level

 width

 width: aNumber

 width: aWidth color: aColor

 displayOn: aGC forDisplayBox: aRectangle

display the borders represented by the receiver in the specified rectangle.
The gc is restored after the draw.

 allSidesEqual: aSmallInteger

true if all four sides have the same border width;
always true here - provided for compatibility

bordered by the receiver, which has bounds of aRectangle.
That is, the argument outset by the receivers borders.
