It does. I can alter it to accommodate the newness.

Here's my suggestions for the checks:

If width > 640 or height > 480:
  RECOMMENDED: Screenshot is wrong size! Detected: WWWxHHH. Maximum
allowed size is 640x480px

If width/height ratio != 4:3 :
   RECOMMENDED: Screenshot dimensions are wrong! Ratio of width to
height should be 4:3.

If width != 600 and height != 450
   RECOMMENDED: Screenshot size should be 600x450, to account for
HiDPI displays. Any 4:3 image size is acceptable, but 600x450 is
preferred.

Discuss.
