The QVector dirtyOnScreenWidgets was aggregated by pointer, which
makes no sense, as a QVector is just as large as a pointer (and even
in Qt 6, when it will be larger, it's not going to be horrible). But
this complicated the code quite a bit.
Aggregate by value instead (it's just one of three such vectors now).
Drive-by fixes:
- use QVector::removeAll() instead of rolling your own
- port two indexed loops to ranged ones. In the first case, it's safe,
as the loop body clearly doesn't touch the iteratee (it's just a
std::accumulate). In the second, the question no longer applies, as
we're now using a consume loop.
