If so, user must specify -vo gl:0 for each film, to set right
slice_height. Or I didn't understood?

{=cut from libvo/video_out.h=}
         *   w,h = width*height of area to be copied (in Y pixels)
         *   x,y = position at the destination image (in Y pixels)
{=end=}
So h is image_height, by meaning. And I check, that It doesn't send
extra lines, in exit-condition of loop (y0<h-slice_height).

And for this case, there is extra glTexSubImage2D call after each loop.
