Support maximumSize for the layout of the text in a QStaticText

Put back maximumSize property in QStaticText to allow matching calls
to drawText with a target rectangle. Implementation is done by
having a dummy paint engine which records the calls to drawTextItem()
and storing these, then replaying them later.
