-  fn glGetProcAddress(p: glfw.GLProc, proc: [:0]const u8) ?gl.FunctionPointer {
-    _ = p;
-    return glfw.getProcAddress(proc);
-  }
-  pub fn draw(window: glfw.Window) !void {
-    const proc: glfw.GLProc = undefined;
-    try gl.load(proc, glGetProcAddress);
-
-    while (!window.shouldClose()) {
-      gl.clearColor(1, 0, 1, 1);
-      gl.clear(gl.COLOR_BUFFER_BIT);
-
