Q_ASSERT will only catch a violation of the precondition of the
checkReverseDirection function in a debug build. This commit replaces
the Q_ASSERT with QVERIFY'ing the precondition (that the widget has a
layout) before calling the function.

* Do not call invalidate from activateRecursive().
This resulted in that a layout was invalidated as many times as there
were items in the layout.
* Several improvements. Do not call resize(size()) too often.
Calling resize() from the widgetEvent() is not very nice though...
* Remove commented out code
* make sure layout is activated even if the widget does not change size
* activate the layout if the resize is same as size()
* In order to not break existing apps, make this an opt-in feature
with QGraphicsLayout::setInstantInvalidatePropagation(true);
