So is the issue that override and final are incompatible?  We're usually not big
fans of final, might prefer to keep override?

Yea, according to cpplint override final is redundant and it suggests removing
override. I switched to removing final and left the override.

   FX_DWORD GetLayoutStyles() const override { return m_dwLayoutStyles; }
   void SetLayoutStyles(FX_DWORD dwLayoutStyles) override;
   void SetFont(IFX_Font* pFont) override;
