A QList<QPair<int,int>> is one of the most dangerous ones, because
it fundamentally changes memory layout, and therefore performance
and invariants, when going from 32-bit platforms (array list) to
64-bit (vector-like).
Port to QVector instead, which has a consistent design across all
platforms.
Also port from QPair to a simple struct { code, depth }, because
member names such as 'first' and 'second' have no semantic value
and make code using them very hard to understand.
