    https://gitlab.synchro.net/main/sbbs/-/commit/a194a15736de98517f48a9b3
    Modified Files:
    src/conio/sdl_con.c
    Log Message:
    Various SDL fixes:

    Pass window size in SDL_USEREVENT_SETVIDMODE
    - Fixes race condition where SDL_WINDOWEVENT_RESIZED or
    SDL_WINDOWEVENT_SIZE_CHANGED arraves while
    SDL_USEREVENT_SETVIDMODE is in the queue

    Set new scaling based on old scaling multiplier
    - Will resize window on mode changes, but tries to keep integer
    multiplier similar. May break fullscreen modes, dunno.

    Have aspect_fix() return higher rather than lower
    - This may make it the same as aspect_correct(), but I'm too lazy
    to figure that out.

    Now that SDL_USEREVENT_SETVIDMODE takes a size, we can clean up sdl_setwinsize() and eliminate another race.

    Modified Files:
    src/conio/sdl_con.c
    Log Message:
    Fix a couple issues found by Coverity

    1) Unreachable return without a lock in sdl_useR_func_ret() (harmless)
    2) LOR in handling SDL_USEREVENT
    - vstatlock was obtained inside of win_mutex which should never
    be done... this could (and likely does) result in a deadlock
    when using SDL mode.

    Modified Files:
    src/conio/sdl_con.c
    Log Message:
    Use a local vstat copy instead of cvstat to avoid holding the lock
    for an extended time. Should fix SDL mode slowness.

    Only call RenderPresent() if we called RenderCopy(). Should fix
    SDL mode flickering.

    src/conio/sdl_con.c
    Log Message:
    Add TODO comment for cvstat.

    When originally created, it was intended to be accessed only by a
    single thread, and therefore not need mutex protection, allowing
    less code to run with vstatlock held. Unfortunately, this is not
    how it turned out, so cvstat should either be removed, or it should
    actually be cleaned up to work as intended.

    Modified Files:

    Log Message:
    Push cvstat into sdl_video_event_thread() stack

    This makes cvstat work as intended, so we no longer need to lock
    vstatlock when accessing it since it's only accessed from the
    video event thread.

    There's still an irritating dependency on vstat for ALT-Enter handling.

    Get vstat out of sdl_add_key() path

    This should almost completely remove vstatlock contention in SyncTERM,
    which should bring SDL output performance close to X11 performance.

    Update fullscreen and mode on Darwin to match window

    This should normalize everything, with the possible exception of
    "zoom" (the thing other OSs call maximized). Ideally, we wouldn't
    allow window size changes when "zoomed" if we could detect the state,
    but it doesn't look like we can.
