fftools/ffplay: do not write out of rdft visualization texture If the window is resized it was possible that xpos pointed outside the visualization texture. By rearranging the overflow check we make sure this (and a crash) does not happen. We also don't have to use xleft for start position, as that is 0 anyways, and if we ever want to take into account xleft then the texture should be positioned accordingly when rendering.
