    tdf#109190 sd: only MakeVisible on mouseclick-up
    
    Since MakeVisible() is called on both
    mousebuttom-down and mousebuttom-up,
    this also eliminates useless double-processing.
    
    In the problematic use case, the user pressed Ctrl-A to select
    a tall table. When clicking to de-select the cells, the contents
    moved around in unexpected ways because the rectangle is at the
    end of the selection during down-click, not at the cursor location.
    The re-arrangment of the screen invalidates the mouse-up,
    so the intended cursor position shifted.
    
    In the bug's calendar example, position the screen so that items
    20-31 are hidden, select the whole month, and then click
    on 5. Before, it would move the screen down to show 31, and
    the cursor would be placed at the screen position where 5
    had originally been. Solved by only repositioning on
    mouse-click up.
    
    However, mouseButtonDown must still be honoured while
    selecting, otherwise you can't select off-screen content
    with the mouse.
    
    This backport contains part of NFC commit b25f5909,
    missing initialization commit
    93bfc16d7d520042f58fa26968a2a9adbbe2afbe
    and cancel MouseSelecting commit
