TTF_SetFontSDF - Enable Signed Distance Field rendering for a font.

       This function is available since SDL_ttf 3.0.0.

       SDF  is  a  technique  that  helps  fonts look sharp even when scaling and rotating, and requires special
       shader support for display.

       This works with Blended APIs, and generates the raw signed distance values in the alpha  channel  of  the
       resulting texture.

       This updates any TTF_Text
        objects using this font, and clears already-generated glyphs, if any, from the cache.
