 *
 * Parameters:
 * id - {String} The element id attribute to set.
 * px - {<OpenLayers.Pixel>} The left and top style position.
 * sz - {<OpenLayers.Size>}  The width and height style attributes.
 * position - {String}       The position attribute.  eg: absolute, 
 *                           relative, etc.
 * border - {String}         The style.border attribute.  eg:
 *                           solid black 2px
 * overflow - {String}       The style.overview attribute.  
 * opacity - {Float}         Fractional value (0.0 - 1.0)
