Actually, with r28058, the problem still seems to exist with -vo gl ...
but not with xv gl2 or sdl.

Also, with -vo x11 (no video scaling), the video isn't centered
properly ... it would appear that videos with width/height ratios
greater than or equal to about 16/9 (1.77) there seems to be an x-axis
offset (left margin), while for the others, a y-axis offset (a top
margin) ... though I haven't been able to find one (in -vo x11) where
both x and y offsets exist. I'm sure this is somehow related to my -vo
xv problem :b.

With 28058 (at least), where only -vo gl suffers from this offset
problem (ie -vo gl2 works), here are some of their differences:

I'm not sure how informative that is :b .... notable differences that I
can see is that the working gl2 has:
  [swscaler @ 0xc41d40]using unscaled yuv420p -> bgr24 special converter
  VO: [gl2] 368x208 => 368x208 BGR 24-bit
while the offset gl has:
  [swscaler @ 0xc41d40]using unscaled yuv420p -> rgb32 special converter
  VO: [gl] 368x208 => 368x208 BGRA
