It's completely negligible compared to the time QPainter::drawText takes, 
which is a pretty complex function.

Actually that doesn't result in a function call as the compiler inlines that 
trivial line of code (access to d->len).

I'd rather go back to the old code and ensure that the call to simpleText() 
becomes a trivial operation by calling it once explicitly in some good place 
Leo probably knows best :)
