Fix loading of web fonts with broken hinting bytecode
The Fira Sans font by the Mozilla Foundation has bytecode that goes into an infinite loop. Fortunately FreeType catches the case, but we fail to render any glyphs and spends too long trying the bytecode on every glyph. This patch instead switches the font to auto-hinting when this error is encountered.
