As part of https://bugs.webkit.org/show_bug.cgi?id=187722, we've made the FontDescriptionRequest slope member an optional to be able to distinguish between "normal" and any other value. However, we also need to look at the FontDescription fontStyleAxis member to distinguish between "italic" and "oblique 20deg". We should have a single tri-state member to distinguish between all these values.
