A printf call was introduced in 20fb008012 that caused the terminal
window to be filled with repeated debugging messages as the window
containing the Qt windowport was resized. I removed it because I
assumed it was meant to be temporary and was left in the commit by
mistake, considering it isn't mentioned in the commit message; if it was
meant to be permanent it'd probably be good to block it out with #ifdef
DEBUG or something at least, because it produces a real deluge of
terminal output if the player spends any time resizing the window by
hand.
