/*! @brief Creates a WebGPU surface for the specified window.
*
* This function creates a WGPUSurface object for the specified window.
*
* If the surface cannot be created, this function returns `NULL`.
*
* It is the responsibility of the caller to destroy the window surface. The
* window surface must be destroyed using `wgpuSurfaceDrop` (wgpu-native) or
* `wgpuSurfaceRelease` (Dawn/emscripten).
*
* @param[in] instance The WebGPU instance to create the surface in.
* @param[in] window The window to create the surface for.
* @return The handle of the surface. This is set to `NULL` if an error
* occurred.
*
* @since Added in version 3.4.
