if I use the following code...
message = TTF_RenderText_Solid( font, "Lorem Ipsum", textColor );
Do I need to free message before I can do this
message = TTF_RenderText_Solid( font, "Lorem Ipsum part 2", textColor );
i.e. does it give me a new surface (and so I have to clean up the old one) or does it just blit over the old one?
