I can't find anything about this on the forum or the web. I've been looking at the font.css styles for a fxl ePub3 and finding that the @fontface code generated when I exported has created two styles (I think) for the same font. Robot Italic is listed along with Robot oblique. Why is that? Do I need both?
It looks like Roboto Thin Italic shows up in .epub as "oblique".
