 * update Color object, according to attributes of  the given xml node.

 * list of available color maps).
 * The two format are mutually exclusive : updating a color with [r,g,b] format will automatically
 * set color index to -1; respectively, setting a zero or positive number for color
 * index will imply setting -1 for r,g,b part of the color object.
 * Color map index should be a zero or positive integer, but no control is done in this method.
 * @param color_ the color to update.

 * @param colorTag_ color attribute. Can be either a [r,g,b] format or an int format (indicating an index into a color map).
 * @param colorMapTag_ color map index. Index of the color map to use.
