The magnitude of the vector formed by the first three texcoords<br>
should not affect the result.<br>
<br>
This turns out to be a significant edge case in the i965 driver,<br>
which normalizes the coords such that the largest component does not<br>
exceed [-1..1], but currently bogusly multiplies the fourth coord<br>
[the array index] as well.<br>

Is this expected? If so, do you have patches planned to fix the problem, or should one of us Intel folks have a look at it?<br>
