Simple display enumerator

Running the attached program gives me this:

Display: 0
  Mode 0: 3520x1200
  Mode 1: 1600x1200
  Mode 2: 1600x1200
  Mode 3: 1280x1024
  Mode 4: 1280x1024
  Mode 5: 1152x864
  Mode 6: 1024x768
  Mode 7: 1024x768
  Mode 8: 800x600
  Mode 9: 800x600
  Mode 10: 720x400
  Mode 11: 640x480
  Mode 12: 640x480

Since I'm running two monitors (1920x1200 and 1600x1200) side-by-side I had expected something like this:

Display: 0
  Mode 0: 1920x1200
  ...
Display: 1
  Mode 0: 1600x1200
  ...

This should probably fix it: http://hg.libsdl.org/SDL/rev/5732e1a80bde

Feel free to reopen in case it does not.
