anv: fix viewport transformation for z component
In Vulkan, for 'z' (depth) component, the scale and translate values for the viewport transformation are: pz = maxDepth - minDepth oz = minDepth zf = pz × zd + oz Being zd, the third component in vertex's normalized device coordinates. Fixes: dEQP-VK.draw.inverted_depth_ranges.* Signed-off-by: Samuel Iglesias Gonsálvez <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Cc: [email protected]
