Add MVKPhysicalDeviceMetalFeatures::mtlCopyBufferAlignment.
Set MTLComputeCommandEncoder label based on Vulkan command type.
Add MVKCommandUse::kMVKCommandUseDispatch.
* Vulkan allows any valid copy regions to be used in this function.
However, Metal's blit command encoder only allows copy offsets and
sizes which are multiples of 4 bytes.
* Before this change, attempting to copy such a region would cause
Metal validation errors to trigger.
* This adds logic to detect such copy regions and uses a special compute
shader to perform a byte-by-byte copy from the source buffer to
the destination buffer with the appropriate offsets.
* This new code path is only needed on macOS, because iOS does not share
the same copy region restrictions.
Load external library versions using script instead of Git submodules.
SPIRV-Cross, Vulkan-LoaderAndValidationLayers & VulkanSamples versions recorded in files.
glslang version determined by Vulkan-LoaderAndValidationLayers.
SPIRV-Tools & SPIRV-Headers versions loaded by glslang.
When MoltenVK is built as part of the LunarG SDK, use external libraries
sourced from parent Vulkan-LoaderAndValidationLayers.
Use Vulkan headers from Vulkan-LoaderAndValidationLayers.
No longer generate Vulkan specification.
Update documentation.
In order to determine the instance version, the 1.1 loader takes
advantage of the fact that a 1.0 ICD will return NULL for
vkGetInstanceProcAddr(NULL, "vkEnumerateInstanceVersion")
SPIRV-Cross supports the macro SPIRV_CROSS_EXCEPTIONS_TO_ASSERTIONS
for builds with exceptions disabled. MoltenVK can support those
builds with just a couple #if statements. When exceptions are
disabled, the program will just abort, not throw.
Add LunarG demo app repository as a submodule.
Add LunarG demo config to makeAll script.
Rename Demos/README_MoltenVK_Demos.md to Demos/README.md.
Do not copy Demos folder to MoltenVK runtime distribution.
Do not copy ThirdPartyConfig.md to MoltenVK runtime distribution.
Add cmake as a dependency in README.md.
GitHub seems to not like markdown without spaces after the `#`-characters.
The [current CommonMark spec](http://spec.commonmark.org/0.27/#atx-headings) says "The opening sequence of # characters must be followed by a space or by the end of line."
This makes these headings render like normal headings on GitHub.
Fix MVKShaderLibrary missing function prototype warning.
Update to latest SPIRV-Cross.
Update to latest Vulkan-Hpp.
Update to latest Vulkan-LoaderAndValidationLayers.
