---------------------------------------
#### MVK_CONFIG_SUPPORT_LARGE_QUERY_POOLS
##### Type: Boolean
##### Default: `1`
Depending on the GPU, _Metal_ allows 8,192 or 32,768 occlusion queries per `MTLBuffer`.
If enabled, **MoltenVK** allocates a `MTLBuffer` for each query pool, allowing each query
pool to support that permitted number of queries. This may slow performance or cause
unexpected behaviour if the query pool is not established prior to a _Metal_ renderpass,
or if the query pool is changed within a renderpass. If disabled, one `MTLBuffer` will
be shared by all query pools, which improves performance, but limits the total device
queries to the permitted number.

Released TBD
- .
- New state tracker implementation.
- New descriptor set/pool implementation.
- The new implementation is less forgiving of applications that don't properly manage the lifetime of their descriptors
(and bind them after the objects they point to have been destroyed).
Use `MVK_CONFIG_LIVE_CHECK_ALL_RESOURCES=1` to revert any crashes this might cause, or mark potentially-destroyed descriptors
with `VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT`.
- Improved occlusion query support:
- Add support for occlusion queries across multiple renderpasses.
- Improve performance by accumulating occlusion quieries in parallel,
and using untracked buffers to avoid encoder serialization.
- New descriptor state tracker implementation to improve performance.
- New descriptor set/pool implementation:
- The new implementation is less forgiving of applications that don't properly manage the lifetime
of their descriptors (and bind them after the objects they point to have been destroyed).
Use `MVK_CONFIG_LIVE_CHECK_ALL_RESOURCES=1` to revert any crashes this might cause,
or mark potentially-destroyed descriptors with `VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT`.
- Added working demo target for VisionOS in Cube Demo.
- Raise minimum target to _macOS 11.0 / iOS 14.0 / tvOS 14.0_
- Add support for `VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT`.
- Reject image usages whose format features are not supported.
- Return `VK_ERROR_OUT_OF_POOL_MEMORY` when running out of descriptor sets.
- Make vkGetPhysicalDeviceToolProperties() an instance function.
- Enable sample LOD bias for Xcode 26.
- Fix VkExternalMemory*CreateInfo not allowing host memory handle types.
- Fix improper boundary error when requesting exactly the number of variable descriptors allocated.
- Fix regression on functions used by multiple extensions.
- Fix improper use of dynamic depth/stencil attachment.
- Fix out-of-bound access when using multiview with multiple subpasses.
- Deprecate configuration parameter `MVKConfiguration::supportLargeQueryPools` and corresponding environment variable
`MVK_CONFIG_SUPPORT_LARGE_QUERY_POOLS`, as obsolete and ignored. Large query pools are now supported always.
- Disable Mac Catalyst builds from `all` and `all-debug` in `Makefile`, due to unresolved issues with Mac Catalyst builds.
- Update to latest SPIRV-Cross:
