oox smartart, cycle matrix: fix too large height in composite algo
The user-level problem was that the height of the entire smartart was
too large. The reason for this was that:
- composite algorithm gets the constraint height should be 77% of width,
this means 6096000 -> 4693920 EMUs
- at the same time the parent container is already smaller, 4064000 EMUs
- a few lines later we already limit the max height with std::min(), but
in the meantime an incorrect y position is calculated, exactly due to
the lack of early limited height
Solve the problem by making sure composite algorithm never works with a
height (even when using it to calculate vertical center) that exceeds
the height of the parent.
