// DXGI Responses from DLLMain
// Because a DllMain function can't guarantee the order in which it loads and unloads DLLs, we recommend that your app's DllMain function not call
// Direct3D or DXGI functions or methods, including functions or methods that create or release objects.If your app's DllMain function calls into a
// particular component, that component might call another DLL that isn't present on the operating system, which causes the operating system to crash.
// Direct3D and DXGI might load a set of DLLs, typically a set of drivers, that differs from computer to computer. Therefore, even if your app doesn’t
// crash on your development and test computers when its DllMain function calls Direct3D or DXGI functions or methods, it might crash when it runs on
// another computer.
//
// To prevent you from creating an app that might cause the operating system to crash, DXGI provides the following responses in the specified situations :
// If your app's DllMain function releases its last reference to a DXGI factory, DXGI raises an exception.
// If your app's DllMain function creates a DXGI factory, DXGI returns an error code.
