VkSurfaceKHR is an alias to `struct something *` on 64-bit platforms, but to
`uint64_t` on 32-bit. Using {} will clear it without running into a type error:

[   88s] sdlglvideo.cpp:294:54: error: cannot convert 'std::nullptr_t' to
'VkSurfaceKHR' {aka 'long long unsigned int'} in initialization
[   88s]   294 |                         VkSurfaceKHR surfacehandle = nullptr;
