You do not get my point...
No matter if my xmodlines are right or wrong...
Not all users are playing fdrpg in fullscreen mode (I am not).
And in windowed mode, I do not want to be stuck to the list of supported
fullscreen modes. I want to use a 800x600 window, even if my video-card does not
support it as a fullscreen resolution (provided that my current screen
resolution is wider than 800x600, for sure...).
