commit dc608751f4bf4c7244d8973bf900bf7b3bd05d91
Author: Vasily Melenchuk <vasily.melenc...@cib.de>

    Update loop prevention in SwContentFrame::MakeAll
    
    In some cases there is an endless loop with just two states
    switchin one into another. To avoid such freeze now 2 last
    states are kept in loop prevention code.
