DW      COLOR           ; Load the current drawing color.

  Input:
     AL         The index number of the current drawing color
     AH         The index number of the fill color

  Return:
     Nothing

The COLOR vector is used to determine the current drawing color. The value
in AL is the index into the palette of the new current drawing color. The
value in the AH register is the color index of the new fill color.
All primitives are drawn with the current drawing color until the color
is changed.

The fill color is used for the interior color for the bar, polygons, pie
slice, and floodfill primitives.
