// ---- LEGACY IE SUPPORT USING FILTERS ----
//  Should IE filters be used or not?
//  PROS: gradients, drop shadows etc will be handled by css.
//  CONS: will harm the site performance badly, 
//        especially on sites with heavy rendering and scripting. 
$useIEFilters: 0; 
// might be 0 or 1. disabled by default.
