 Hello all.  First time here, and first of all thank you for a
 marvelous program in ffmpeg.

 I have noted the following behavior:

 With this bmp (bgr24) [1], if I use ffplay on it ($ ffplay
 mostly_white.bmp), the white border displays
 "darkened" or "with an added red hue" for whatever reason (you can see
 this effect within the image itself).

 [1] http://rogerdpack.t28.net/incoming/mostly_white.bmp the "white"
 outermost backgrounded window looks somewhat red (here's an
 example output http://rogerdpack.t28.net/incoming/red_hue.bmp to compare)

 Here's the command line output (mingw build, but it seems to reproduce
 with all platform/versions I have tried).
