After analysing text drawing performance two things seem to take up most
of the time. The first is font lookup, the second is QVector
initialization.
To address the first point a per paint engine instance font cache is
introduced. At the moment no mechanism exists to clear this cache and
it is unbounded.
To address the second point, we simply switch to using QVarLengthArray
instead of QVector.
In an artificial benchmark that draws text in a tight loop, the first
change raised fps from ~70 to ~100. The second change further raised this
number to ~115 fps.

and at the same time they may not want a random delay in the program
(due to the pattern getting optimized at a random usage).
So: add an optimize() call to force an immediate pattern optimization,
and a pattern option to force an optimization on the first usage.
