Summary: SDL_SetWindowMaximumSize fails if Width or Height is equal to minimum Height or Width

Basicly there is problem and somewhat a solution: https://discourse.libsdl.org/t/setwindowmaximumsize-bug/28267 

If you SDL_SetWindowMaximumSize() after SDL_SetWindowMinimumSize() with one of axes have the same value, function will have no effect. 

This: (line 2144@SDL_video.c)
if (max_w <= window->min_w || max_h <= window->min_h) {
    SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
    return;
}

May be changed to this:
if (max_w < window->min_w || max_h < window->min_h) {
    SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
    return;
}

I dont know if solution may cause platform-specific problem.
Cheers
