test code to recreate bug

You can create and destroy renderers using the same window, without having to destroy and create the window again, yes? I believe I've exposed a bug where SDL_CreateRenderer will fail when creating a software renderer when previously one has been created and destroyed. Perhaps the problem is in software renderer clean-up code related to the window?

The attached main.cpp will re-create the bug every time on Windows 10, Android, and presumably all platforms.

The test code cycles through all available renderers when you press the space key, destroying and creating a new renderer next in the list, eventually coming to the software renderer.
