Only 64-bit windows is tested, and there are still various failures, but QF is limping along in windows again. nq-sdl works for sw, and sw32, gl and glsl are mostly black (but not entirely for gl?), vulkan is not supported with sdl. nq-win works for sw and sw32, and sort of for vulkan (very dark and upside-down?). gl and glsl complain about vid mode, qw-client-[sdl,win] seem to be the same, but something is wrong with the console (reading keyboard input).
