Method ShaperImpl

src/SFML/Graphics/Text.cpp:199–207

HarfBuzz font objects are linked to a specific FreeType face and a specific character size If we need to shape text using another font or another character size we will have to create a new shaper

    // If we need to shape text using another font or another
    // character size we will have to create a new shaper
    ShaperImpl(void* fontHandle, std::uint64_t theFontId, unsigned int theCharacterSize) :
        fontId(theFontId),
        characterSize(theCharacterSize),
        shaper(hb_ft_font_create(static_cast<FT_Face>(fontHandle), nullptr)),
        shapingBuffer(hb_buffer_create())
    {
        // Make HarfBuzz use FreeType font functions
        hb_ft_font_set_funcs(shaper.get());
    }

    // To save on memory, instead of every sf::Text object having
    // its own shaper, we try to share shapers among multiple
