Fix use-after-free when pumping the event loop after SDL_DestroyWindow()

Closing the window is asynchronous, but we free the window data immediately,
so we can get an updateLayer callback before the window is really destroyed which
will cause us to access the freed memory.

Clearing the content view will cause it to be immediately released, so no further
updateLayer callbacks will occur.

     3 # This is the script buildbot.libsdl.org uses to cross-compile SDL2 from
     4 #  x86 Linux to Raspberry Pi.
     5 
     6 # The final tarball can be unpacked in the root directory of a RPi,
     7 #  so the SDL2 install lands in /usr/local. Run ldconfig, and then
     8 #  you should be able to build and run SDL2-based software on your
     9 #  Pi. Standard configure scripts should be able to find SDL and
    10 #  build against it, and sdl2-config should work correctly on the
    11 #  actual device.
