 then some of the graphics are saved to the local file system and freed in the memory.

    Optimize ImplCheckSizeOfSwappedInGraphics() a bit
    
    Store used size as a member so we don't need to recalculate it
    all the time and no need to use a size map.

    Remove HTML swapped out image export tests
    
    It crashes on master for some reason. Since it's not
    in our main focus it's simpler to remove it.
