Fixed bug 1859 - No SDL_VIDEORESIZE event generated when the window manager sets the window size.

Just confirming that the patch from Andreas (attachment 1715 [details]) works for me under SDL 2.0.3 with xmonad.

Confirming that the patch in this ticket fixes the full-screen switching for dosemu2 on ubuntu-16.04. Note that I am not using xmonad, so this bug appears to be generic.
