This extension removes the VkViewport
maxDepth restrictions that the values must be between
It also removes the same restriction on
Finally it removes the restriction on the
depth value in
RESOLVED: The behavior described in Primitive
Clipping still applies.
If depth clamping is disabled the depth values are still clipped to 0
≤ zc ≤ wc before the viewport transform.
If depth clamping is enabled the above equation is ignored and the depth
values are instead clamped to the VkViewport
maxDepth values, which in the case of this extension can be outside of
2) What happens if a resulting depth fragment is outside of the
1.0 range and the depth buffer is fixed-point rather than floating-point?
RESOLVED: The supported range of a fixed-point depth buffer is
1.0 and depth fragments are clamped to this range.
