-- == Description
--
-- This extension removes the 'Vulkan.Core10.Pipeline.Viewport' @minDepth@
-- and @maxDepth@ restrictions that the values must be between @0.0@ and
-- @1.0@, inclusive. It also removes the same restriction on
-- 'Vulkan.Core10.Pipeline.PipelineDepthStencilStateCreateInfo'
-- @minDepthBounds@ and @maxDepthBounds@. Finally it removes the
-- restriction on the @depth@ value in
-- 'Vulkan.Core10.CommandBufferBuilding.ClearDepthStencilValue'.
--
-- == New Enum Constants
--
-- -   'EXT_DEPTH_RANGE_UNRESTRICTED_EXTENSION_NAME'
--
-- -   'EXT_DEPTH_RANGE_UNRESTRICTED_SPEC_VERSION'
--
-- == Issues
--
-- 1) How do 'Vulkan.Core10.Pipeline.Viewport' @minDepth@ and @maxDepth@
-- values outside of the @0.0@ to @1.0@ range interact with
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#vertexpostproc-clipping Primitive Clipping>?
--
-- __RESOLVED__: The behavior described in
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#vertexpostproc-clipping 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 'Vulkan.Core10.Pipeline.Viewport' @minDepth@ and
-- @maxDepth@ values, which in the case of this extension can be outside of
-- the @0.0@ to @1.0@ range.
--
-- 2) What happens if a resulting depth fragment is outside of the @0.0@ to
-- @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 @0.0@
-- to @1.0@ and depth fragments are clamped to this range.
