I have a question concerning the pixel visibilty test order.

Is it right that only the Z-test is performed before the pixel shader on new graphicchips (R360/400 and NV40)?
And only, if the depth value is not modified in the pixel shader.

And that the stencil and scissor test is already performed after the pixel shader, so there is no skipping of unnecessary pixel shader program execution?
