SDL_TTF: No function for checking scalable fonts

Hi,
There’s no function to check for whether the font is scalable or not in
SDL_ttf. I feel its better to have a function for checking the scalability
of the font as below.

int TTF_FontFaceIsScalable ( const TTF_Font *font )
{
return (FT_IS_SCALABLE ( font->face ) );
}–
