* Rewrite feature handling, include all Vulkan 1.1 and 1.2 features
* Fixes
* Move features.rs to device module
* More small fixes
* Changelog
* Convert trait `ShaderInterfaceDef` into struct `ShaderInterface`
* Convert some instances of PipelineLayoutDesc to RuntimePipelineDesc
* Use regular Vec for now
* Convert PipelineLayoutDescUnion to RuntimePipelineDesc
* Convert PipelineLayoutDescTweaks to use RuntimePipelineDesc
* Remove PipelineLayoutDesc trait, replace with what used to be RuntimePipelineDesc
* Remove PipelineLayoutAbstract trait
* Fix bug
* Provide value for push constants to entry point instead of type
* Remove GraphicsEntryPointAbstract, allow pipelines without fragment shader
* Move descriptor::pipeline_layout to pipeline::layout
* Small changelog addition
* Fix bug
* vulkano/image: SampleCounts for each pixel in an Image.
Map u32-bit SampleCountsFlagBits type to boolean collection of
SampleCounts struct type.
* vulkano/image: Convert between vk::SampleCountFlags and SampleCounts
* Move physical device functions into their own module
* Add method to FunctionPointers to query Vulkan api version
* Store the versions of instances and devices, allow user to query
* Check Vulkan version in vulkano-shaders, changelog
* Small mistake in changelog
* Add core instance extensions.
core extensions added as part of `vulkano::instance::InstanceExtensions`
VK_KHR_device_group_creation
VK_KHR_external_fence_capabilities
VK_KHR_external_memory_capabilities
VK_KHR_external_semaphore_capabilities
VK_KHR_get_display_properties2
VK_EXT_acquire_xlib_display
VK_EXT_debug_report
VK_EXT_direct_mode_display
VK_EXT_display_surface_counter
* export FunctionPointers::entry_points method.
Similar to PhysicalDevice.instance().pointers() export root-level
entry_points() method. This will allow applications to call vk-functions
like `vkEnumerateInstanceExtensionProperties` directly.
* heap: Add MEMORY_HEAP_MULTI_INSTANCE_BIT for MemoryHeap.
A new method is_multi_instance() method is added to `MemoryHeap` to
know whether the heap is enabled for multi-instance.
* CHANGE-LOG.
* Remove format structs, StrongStorage trait
* Remove a bunch of superfluous traits and functions
* Remove FormatDesc trait
* Make formats macro a bit easier to read
* Rename AcceptsPixels trait to Pixel, reverse implementation direction
* Changelog
* Documentation
* Improved image aspects, add aspects to Format
