 Ooops. Looks like it was my fault afterall... And I trying to blame another 
guy... :P
 Anyway, I guess this was a good opportunity for an auditory checking and 
fixing of others memory leaks, so it was a good thing, afterall. :)

 About the cache of textures, that is not practicable, since text is different 
all the time. You'd need tons of memory to cache all different combinations 
of texts.
 What I currently do is to cache TTF_Font, which already helps speeding it up. 
Though, I dunno if TTF_OpenFont() is all that expensive.

 By the way, Ingo, the game is outputting this:
