Make QStaticText layout lazy
To avoid the unnecessary overhead of doing the text layout every time
a part of the QStaticText object is changed, we mark it as invalid
instead and do the layout when we have to. This means an overhead on
the first paint event for most users. The overhead can be avoided by
using the QStaticText::prepare() function and will probably not be
noticable anyway, since it's a one-time thing.
