David Gow 35c1bbfa49 SDL_stdinc.h: Add an SDL_clamp() function 
Add a function to clamp a value to a range.

SDL_clamp(x, a, b) is equivalent to SDL_min(a, SDL_max(x, b)): it
ensures that x is not smaller than a, nor larger than b.

While, as best I can tell, this isn't actually standardised anywhere,
it's a very useful function/macro to have.
