Description

This extension allows the getPhysicalDeviceSurfaceFormatsKHR and getPhysicalDeviceSurfacePresentModesKHR functions to accept NULL_HANDLE as their surface parameter, allowing potential surface formats, color spaces and present modes to be queried without providing a surface. Identically, getPhysicalDeviceSurfaceFormats2KHR, getPhysicalDeviceSurfacePresentModes2EXT, and getPhysicalDeviceSurfaceCapabilities2KHR would accept NULL_HANDLE in PhysicalDeviceSurfaceInfo2KHR::surface. __This can only be supported on platforms where the results of these queries are surface-agnostic and a single presentation engine is the implicit target of all present operations__.
