Remotely triggerable WIN32K freetype assert

ros 0.4.9-RC-35-g3eb03ef

I can make ros assert in WIN32K freetype remotely via webbrowser. This is 100% reporducible for me.

Reproduction steps
-Install ros
-Install Opera 12.18 from rapps
-browse to www.palemoon.org

*** Assertion failed: style_name

***   Source File: ../../win32ss/gdi/ntgdi/freetype.c, line 4031

It will assert in freetype over and over, I took the bts in react.log
when I finally *t*erminate the thread, ros will BSOD.

I consider this critical, because most likely we do not have much time (before the website changes) and this has dramatic security implications ofc.
