Re: Switching rendering method at runtime

Not much trickery though:

I remember destroying renderers and recreating them without issue to
switch between OGL and Software at runtime. Works exactly as you'd
expect it. Of course you need to download & re-upload/recreate all
SDL_Texture's on-the-fly yourself, but if you wrapped them in some
custom wrapping struct instead of using SDL_Texture's directly with
some global list of all your structs it's not that hard to do.

I don't recall if I destroyed the window as well, but again that's not
really hard to do in addition if it doesn't work without doing that.
 Just obtain old size, and resize new window immediately to old size
again. The only effort is really re-creating textures as described
above.
