My email client is broken and includes the finishing dot(.) into the url.

I tried your new patch.

1) with my old 16bit/pixel ppm: No effect,
the image is the same as when specify an inexisting texture.

2) with a new 32bit/pixel float-ppm. This is no official format,
I just supplied a 32 bit float (range 0..1) for each component of a pixel.
I had to further patch gl_common.c in order to be able to load this texture.
But there is again no effect, the same as when specify an inexisting texture.

I wonder what is going wrong. I even used ARB_precision_hint_nicest because I
have read ARB_precision_hint_fastest will make 16-bit-floats. No success.

I give the VO-related output of mplayer:
