For the option when we use the SDL_Renderer we change:
- the order of calls to SDL_DestroyTexture/Renderer.
Reported by valgrind on linux as an error to destroy the
renderer before the texture.
- the SDL_Renderer and texture are created when the surface is
initialized before the window is shown
It seems that creating the SDL_Renderer and Texture between the
moment the window was shown and the renderer present was introducing
a flashing blank window because of the time taken to create the
renderer/texture resources.
