Enable text layout drawing on coordinates outside QFIXED_MAX

In an earlier commit, painting on such coordinates was rejected, since
it would overflow the internal calculations using QFixed. Instead,
avoid the overflow by translating the painter to avoid the huge
coordinate values.
Also reduce the max value somewhat, so that pos stays well away from
QFIXED_MAX, to avoid overflows in the other QFixed variables that have
values offset from pos.
