To correct this, OSystem_SDL_Normal::hotswap_gfx_mode() must be
adjusted to also backup & restore the overlay data if any.

This is complicated by the fact that the old sdl_tmpscreen might be in
555 mode while the new one is in 565 mode - so simply doing a
memcpy won't work.

Idea: optimize hotswap_gfx_mode to not just call unload_gfx_mode()
and load_gfx_mode(). Rather, be more clever, and keep the old
sdl_tmpscreen around for a while, so that we can use SDL to blit from it
to the (equally sized) new tmpscreen. SDL should then perform any
conversion that are needed.
