/**
 * Progressive Enahncement to use SVG sprites with PNG fallback for IE6+7
 *
 * The trick:
 * Legacy IE does not support rgba values.
 * By defining a rgba background color together with the
 * SVG background image for all modern browsers, legacy IE 
 * will ignore the SVG and use the 
 * first background definition containing the fallback PNG 
 *
