Image not always centered in fullscreen

Hi,

I found a problem on windows. When I use a screensize which isnt supported
directly in hardware the image is not always centered. It seems to be a problem
when the width is supported, but not the height. For example when I use 640x272
the image starts at the top, when I use 481x272 the image is centered. I did not
try a non supported width with a supported height. I’m using SDL 1.2.
