Public Member Functions
void	create (const VulkanCore &core, vk::ImageView depth, vk::Extent2D depth_extent)
	After a wait for idle since an in flight frame may still read the previous pyramid.
void	record (vk::CommandBuffer cmd, vk::Extent2D scene_extent, const glm::mat4 &view_projection)
	Depth in depth_sampled and only its top left `scene_extent` is reduced.
void	beforeRead (sync::BarrierBatch &barriers)
	Earlier writes land before a compute shader samples view().
auto	isReady () const -> bool
	view() can be bound without it but only a ready pyramid is ever built
auto	view () const -> vk::ImageView
	Every level in eShaderReadOnlyOptimal once recorded.
auto	sampler () const -> vk::Sampler
auto	builtExtent () const -> vk::Extent2D
	What the last record() covered and saw with zero levels before the first one.
auto	builtLevels () const -> uint32_t
auto	builtViewProjection () const -> const glm::mat4 &

Static Public Member Functions
static auto	levelCount (vk::Extent2D extent) -> uint32_t
	Levels until the scene extent halves down to one texel.

Static Public Attributes
static constexpr uint32_t	k_max_levels = 13
	Mirrors hiz_reduce.slang kMaxLevels so level 0 reaches 4096 texels.
