OK, I understand the  fix in CharacterBlockScanner because it is better
explained in DisplayScanner:
sending stopConditions will initialize alignment inst. var., which for some
reasons wasn't set in MVC...
Not sure that this is the right fix though... And not sure how this works
in Morphic too...

I however have found more glitches in Morphic:
1) if alignment is centered, you can set the blinking cursor to the left of
the window by double clicking very near the left border.
    Normally, the cursor should go the left of leftmost character...
    I suspect that this could be an unset alignment defaulting to left flush
    (seing all these alignment ifNil:[textStyle alignment] is a clue)

2) in case of WideString, you cannot easily select the leftmost character
in a centered line by help of the mouse (unless you go left to window
border).
    I found that this is due to the leftMargin test in line from
scanMultiCharactersFrom:...
        nextDestX > rightX ifTrue: [destX ~= leftMargin ifTrue: [^stops
crossedX]].
    It did work OK when this was firstDestX, so it's me who broke it with
Multilingual-nice.179
    Indeed, only a MultiCompositionScanner would initialize firstDestX :=
leftMargin, while the other scanner let it nil...

3) The blinking cursor vanishes when cursor is moved at the right of a
right flushed line.
    it even vanishes sooner if last char is blank (space/tab) and the
cursor is moved with arrow key (different from mouse click!)
