Qt Quick Controls Re engineered
summary
Reengineered Qt Quick Controls strips per-instance QML objects (menu, action, tooltip timers) and moves event handling and lifecycle work into C++ to cut runtime overhead; creation time improves by roughly an order of magnitude on an entry‑level Raspberry Pi while memory use drops similarly. The new API exposes minimal templates and an item‑based styling model with background and label items that the control takes ownership of and destroys when replaced, and replaces heavy ScrollView with attachable scroll bars for light, composable lists.
