Bug#570333: stix fonts for mathml iceweasal

[jagginess <jagginess@videotron.ca>]

I discovered that after unzipping the provided link to the stix zip file 
into ~/.fonts, running fc-cache -f ~/.fonts
then restarting iceweasal, that mathml webpage showed correctly

In addition to my original message, perhaps a new package for stix 
should be requested?

Thank you for looking into this..

(There's also a wikipediapage about it, and says license for stix is 
royalty-free)
