The layer needs functionality that is not part of Vulkan 1.0 and is provided by either Vulkan 1.1 or separate Vulkan extensions. The layer used to solve this issue by bumping the API version passed by the application in VkCreateInfo to 1.1 if this was set to 1.0. This workaround does not seem to be working anymore with recent versions of the loader. Fortunately, the loader now allows layers to change the extension lists passed by the application. This patch changes the layer to use this approach and removes the API bump logic. Documentation is updated accordingly.
