I was just diffing fglrx and r300g output for my rv530 and this was on the list.
I'm wondering what we would need for this? does TGSI have the
necessary bits? I assume there would be a bit of work in the GLSL
compiler also.
It would mostly be GLSL work.
We already have the underlying TXD instruction which takes the partial
derivative operands.
It shouldn't be too hard for someone to do - just follow the example
of the existing GLSL texture() functions.
