toggle currently active fullscreen mode and leave

Trying to go straight forward from one fullscreen mode to another make things more complicated to control. 
Seems a full loop is required when trying to change fullscreen modes and window size properly for now.
Maybe will restore the ability to jump from one fullscreen mode to another when more cleaning will be done deeper in the rabbit hole.
