 +==== Description of bar ==== 
 +<code c>
 +bar draws a filled-in, rectangular, two-dimensional bar. The bar is
 +filled using the current fill pattern and fill color. bar does not
 +outline the bar; to draw an outlined two-dimensional bar, use bar3d with
 +depth equal to 0.
 +The upper left and lower right corners of the rectangle are given by
 +(left, top) and (right, bottom), respectively. The coordinates refer to
 +pixels.
