we can build a window app!

build type must be set to Release or it's horribly slow, and fullscreen does not work

+ * Dynamically load the Vulkan loader library.
+ *
+ * This should be called after initializing the video driver, but before
+ * creating any Vulkan windows. If no Vulkan loader library is loaded, the
+ * default library will be loaded upon creation of the first Vulkan window.
+ *
+ * It is fairly common for Vulkan applications to link with libvulkan instead
+ * of explicitly loading it at run time. This will work with SDL provided the
+ * application links to a dynamic library and both it and SDL use the same
+ * search path.
+ *
+ * If you specify a non-NULL `path`, an application should retrieve all of the
+ * Vulkan functions it uses from the dynamic library using
+ * SDL_Vulkan_GetVkGetInstanceProcAddr unless you can guarantee `path` points
+ * to the same vulkan loader library the application linked to.
+ *
+ * On Apple devices, if `path` is NULL, SDL will attempt to find the
+ * `vkGetInstanceProcAddr` address within all the Mach-O images of the current
+ * process. This is because it is fairly common for Vulkan applications to
+ * link with libvulkan (and historically MoltenVK was provided as a static
+ * library). If it is not found, on macOS, SDL will attempt to load
+ * `vulkan.framework/vulkan`, `libvulkan.1.dylib`,
+ * `MoltenVK.framework/MoltenVK`, and `libMoltenVK.dylib`, in that order. On
+ * iOS, SDL will attempt to load `libMoltenVK.dylib`. Applications using a
+ * dynamic framework or .dylib must ensure it is included in its application
+ * bundle.
+ *
+ * On non-Apple devices, application linking with a static libvulkan is not
+ * supported. Either do not link to the Vulkan loader or link to a dynamic
+ * library version.
+ *
+ * \param path The platform dependent Vulkan loader library name or NULL
+ * \returns 0 on success or -1 if the library couldn't be loaded; call
+ *          SDL_GetError() for more information.
