sdl2: restore window dimensions by resize
instead of destroying and recreating window, fixes segfault caused by handle_keyup trying to access no more existing window when using Ctrl-Alt-U to restore window "un-scaled" dimensions Thread 1 "qemu-system-x86" received signal SIGSEGV, Segmentation fault.
