texture good

Hello Alex,

I'm a developper of PCSX2 and made some tests on my side. I think I understand
the cause of the bad rendering. 

At the beginning of the program we upload a float texure (see attachment). I
ask Lukk to dump the texture with glGetTexImage (see attachment). If you
compare both textures, we will see that some floats were rounded.
I upload Lukk's texture and I can confirm you that we got same rendering issue. 

The upload of the texture is fine on my HD5770 with mesa 8.0.5. So the issue
feel chip specific.

Cheers.
