- Ensure Vulkan loader magic number is set every time before returning any dispatchable Vulkan handle.
- Fix crash when `VkDeviceCreateInfo` specifies queue families out of numerical order.
- Fix crash in `vkDestroyPipelineLayout()`.
- `vkCmdBlitImage()` support format component swizzling.
- `vkCmdClearImage()` set error if attempt made to clear 1D image, and fix validation of depth attachment formats.
- Remove error logging on `VK_TIMEOUT` of `VkSemaphore` and `VkFence`.
- Consolidate the various linkable objects into a `MVKLinkableMixin` template base class.
