Example of stretching for msup, msup, msubsup

msup/msup need to share the same implementation with msubsup so that they stretch operators.

testcase 2

The current testcase is invalid. integral is not stretchy by default per the op dict, so it should not stretch.

I attach a correct testcase testing either

- that integrals in display style are drawn larger (they are largeop per the op dict)
- integrals with stretchy="true" next to a tall <mspace/> stretch.

This works on Linux (and assumes that Latin Modern fonts are installed).

Anyway, the bug was about inconsistencies between msubsup/msub/msup, which should not happen anymore since they all use a RenderMathMLScripts.
