In order to improve consistence within portage, the mozsvg USE flag should be renamed to svg. I see no actual reason to seperate the two anymore, as svg support is not experimental anymore in firefox (mozilla). Whoever doesn't want svg on an otherwise svg-enabled system could still put it in package.use Reproducible: Always Steps to Reproduce: 1. 2. 3.
The flag was removed completely. http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/mozconfig-2.eclass?r1=1.9&r2=1.10
