-----------
Fix #27048: text + SimpleDeform modifier = weird render result!
It's not real fix, just patch which makes things better by using average
normal for each displist separately. There are still some artifacts with
quite highly deformed letters "O" or "g", but correct fix would need
to calculate derivative of modifiers, which isn't implemented yet.
