22 # This code is used to pass on device (including physical device) extensions through the call chain. It must do this without
23 # creating a stack frame, because the actual parameters of the call are not known. Since the first parameter is known to be a
24 # VkPhysicalDevice or a dispatchable object it can unwrap the object, possibly overwriting the wrapped physical device, and then
25 # jump to the next function in the call chain
