     * Some of the logic is 'hardwired' even though it really depends on the
     * image.  If we wanted flexibility then we'd need to create an ImageXXX
     * that, given the status region, would return the predominant color or
     * average of colors in that region.  A Color map could then be used to
     * figure out what text color would provide good contrast.
     * 
     * I didn't do that... and mozilla doesn't do that.  Here's their code:
     *
	 *    // The splash screen background is black, so use white text
	 *      dc.SetBkColor(RGB(0,0,0));
	 *      dc.SetTextColor(RGB(255,255,255));
	 *
	 * Anyway, this is just to explain the motivation between the 'hardwired'
	 * values.  The same applies to the STATUS_BOTTOM_INSET defined above.
