'Set the video scaling factor. That is the ratio of the number of pixels on
screen to the number of pixels in the original decoded video in each
dimension. Zero is a special value; it will adjust the video to the output
window/drawable (in windowed mode) or the entire screen.
Note that not all video outputs support scaling.
@param f_factor: the scaling factor, or zero.'
