taking into consideration variations across MTLDevice Features Sets.
Simplify contents and names in MVKMTLFmtCaps enum.
Add MVKVkFormatFeatureFlags enum to map capabilities from MVKMTLFmtCaps to VkFormat.
Derive three VkFormatFeatureFlags in VkFormatProperties from documented
MTLPixelFormat capabilities, customizing based on MTLDevice feature sets.
Include VK_FORMAT_FEATURE_STORAGE_IMAGE_ATOMIC_BIT and
VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_ATOMIC_BIT in writable features.
MVKPixelFormats modify VkFormatProperties unit test to log differences.
MVKPixelFormats build and modify Metal format maps before building Vulkan format maps.
MVKMTLFormatDesc remove sinceOSVersion and isSupported() checks format caps instead.
Remove datafilling of OS versions in MVKMTLFormatDesc.
MVKPixelFormats improve readability of datafilling of VkFormat, MTLPixelFormat,
and MTLVertexFormat capabilities using dynamic symbol macros to allow abbreviations.
Add MVKMTLFmtCaps enum to track MTLPixelFormat capabilities, and populate table of
default MTLPixelFormat and MTLVertexFormat capabilities.
Add mvkSelectPlatformValue() template function to support
selecting values based on the OS platform.
Replace getMTLPixelFormatFromVkFormat() in MVKDevice, MVKDeviceTrackingMixin
and MVKCommand with access to getPixelFormats().
Add mvkPlatformPixelFormats() to support default platform pixel format info.
Rename MVKFormatDesc to MVKPlatformFormatDesc in mvk_datatypes.mm to avoid
naming conflict.
Wrap MVKCommandBuffer::prefill() in autoreleasepool.
For non-reusable MVKCommandBuffers, release command instances
once prefilling is done to reduce memory pressure.
Change mvkClear() & mvkCopy() to accept array size.
Fix clearing of array content using mvkClear().
Update number of VkDynamicStates that can be tracked.
Change copying of sizeable structs in vk_mvk_moltenvk.mm.
Add mvkAreEqual() to compare values, structs and arrays.
query number within a single MTLRenderEncoder.
Track MTLRenderEncoder used for each query and validate query is not reused within the
scope of a single MTLRenderEncoder, logging error and ending current query if encountered.
Remove _t from pre-typedef struct declarations.
Move declaration of MVKSwapchainImageAvailability from MVKImage.h to MVKSwapchain.h.
Update What's New document.
Add MVK_CONFIG_PREALLOCATE_DESCRIPTORS env var to enable descriptor preallocation
in pool. Add MVKDescriptor subclasses for all used VkDescriptorType values.
Support allocating MVKDescriptor subclasses via direct instantiation,
or referencing preallocated instances held in a fixed collection.
MVKDescriptor subclasses support resetting and reuse from preallocated collection.
MVKDescriptorPool optionally holds collections of preallocated descriptors,
one collection per VkDescriptorType value.
Support VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT to mark preallocated
descriptors as available when freed.
