MVKCmdClearAttachments support clearing multiple attachment layers.
MVKCmdClearImage use renderpass clear, and support clearning multiple image layers.
Rename mvkCmdClearImage() to mvkCmdClearColorImage().
MVKDevice add getFormatIsSupported() to allow devices to test for format support.
MVKFramebuffer support multiple layers.
mvk_datatypes.h support both 2D and 3D mipmap calculations and allow
mvkMTLPrimitiveTopologyClassFromVkPrimitiveTopology() in iOS.
Remove support for VK_FORMAT_B10G11R11_UFLOAT_PACK32 & VK_FORMAT_E5B9G9R9_UFLOAT_PACK32
since format components are reversed on Metal.
Move OS extension source files to new OS directory.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.16.
On iOS, only compile IOSurface support, and link IOSurface framework to
libMoltenVK.dylib, if IPHONEOS_DEPLOYMENT_TARGET is at least iOS 11.0.
Update to latest version of SPIRV-Cross.
Update MoltenVK version to 1.0.15.
Support separate specialization for each workgroup dimension.
Support zero as a specialization ID value.
Cleanup MoltenVKShaderConverterTool.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.14.
Set CAMetalLayer magnificationFilter property to Nearest by default.
Add MVKDeviceConfiguration::swapchainMagFilterUseNearest member to allow overrides.
Map 1D buffer view contents to 2D Metal texture.
Add MVKPhysicalDeviceMetalFeatures::maxTextureDimension element.
Set VkPhysicalDeviceLimits::maxTexelBufferElements to maxTextureDimension ^ 2.
Shaders accessing buffer view use special function to map 1D buffer view coordinates
to 2D Metal texture coordinates.
Pass maxTextureDimension to shader.
Update to latest SPIRV-Cross version for appropriate shaders.
Update MoltenVK version to 1.0.13.
MVKDeviceMemory track MVKImages and MVKBuffers separately.
Per Vulkan spec, restrict linear images to 2D, non-array, single mipmap.
Use texel buffer if possible for texture on coherent device memory.
Only flush MVKImages (not MVKBuffers) when device memory mapped.
Do not flush texel buffer images.
MVKDeviceMemory uses a single memory allocation, which may be an MTLBuffer or host memory.
Image populates MTLTexture when bound to host accessible device memory.
Update MoltenVK version to 1.0.10.
Move surface access to UI components to main thread.
Fix deadlock possibility between MVKFence and MVKFenceSitter.
Fix handling of locking on deferred-destruction objects.
Update MoltenVK version to 1.0.9.
Add MVKDeviceConfiguration::synchronousQueueSubmits configuration setting.
Update to latest SPRIV-Cross version to fix atomic_compare issue.
Update MoltenVK version to 1.0.8.
Add MVKDeviceConfiguration::metalCompileTimeout config setting.
Limit Metal compilation timeouts to 125 ms by default in Release mode.
Invoke Metal library, function specialization, and pipeline compilations
asynchronously with completion handlers. Abort after timeout expires.
Set default value of MVKDeviceConfiguration::supportLargeQueryPools to true,
to support large Query Pools by default.
Access vertexDescriptor in MTLRenderPipelineDescriptor only if needed.
Update MoltenVK version to 1.0.7.
Move MVKQueueFamily to MVKPhysicalDevice. Cache MTLCommandQueues in MVKQueueFamily
and assign to MVKQueues as they are created.
Refactor performance tracking. Replace vkGetShaderCompilationPerformanceMVK()
with vkGetPerformanceStatisticsMVK() and associated structures.
Add MTLCommandQueue access performance tracker.
Update MoltenVK version to v1.0.6.
Dynamically create frag shaders for clearning attachments and images.
Dynamically create frag shaders for blitting scaled images.
MVKGraphicsPipeline don't create MTLRenderPipelineState if vertex function conversion fails.
MVKComputePipeline don't create MTLComputePipelineState if compute function conversion fails.
Handle SPIRV-Cross errors thrown during SPIR-V parsing in compiler construction.
Set undefined property limits to large, but not max, values to avoid casting issues in app.
Mark multiDrawIndirect features as available.
Update to latest SPIRV-Cross version.
Update to MoltenVK version 1.0.5.
As the feature flags get more complicated, it will be better to just
leave these blank rather than guess what the flags might be if/when
Metal supports their corresponding configs in the future.
Helps to fix#147
