What is difference between using near flag (get non-html related in options)
versus using following filters that are provided by default:

+*.png +*.gif +*.jpg +*.css +*.js -ad.doubleclick.net/*
-mime:application/foobar

Has above filter line became obsolete? I notice in previous threads people are
told to use Near flag instead of this filter line, but why? What is
difference?
Merci.
