[SDL] SDL_ttf not taking const pointers?

I was going to reply that SDL_ttf is a C (not C++) library and probably doesn't
However, I looked at the code and it *does* use "const" in several places (at
least for const char pointers).
Also, here is the source for TTF_FontHeight():
int TTF_FontHeight(TTF_Font *font)
Obviously, "const" would work fine in this case. Maybe you should try to
contact the SDL_ttf author. You might even download the source and take a
crack at the changes yourself...
