Pass localPos to deliverHoverEventRecursive, deliverHoverEventToItem and sendHoverEvent, so that deliverHoverEventRecursive() can merely transform from its own coordinate space to each child's space by calling itemToParentTransform(). That doesn't require up-the-tree recursion like mapFromScene() does. Apply the same trick to QQuickWindowPrivate::findCursorItemAndHandler(). Apply the same trick to QQuickPointerHandler::parentContains(local, scene): now QQuickPointerHandler::parentContains(QEventPoint) also calls that with both local and scene positions, which it already has, so this likely optimizes some use cases outside of the hover and cursor cases. But to make that work, we need to apply the same trick to QQuickDeliveryAgentPrivate::eventTargets() as well, and now it needs to localize the QEventPoint before calling the predicate. Usually, global position is QGuiApplicationPrivate::lastCursorPosition; but when no mouse events occur, only touch events, lastCursorPosition may remain offscreen. So we use the QEventPoint::globalPosition when possible; so it's useful to pass globalPos along to each of these hover functions, so that deliverHoverEventToItem() can construct the QMouseEvent with it, and sendHoverEvent() can construct the QHoverEvent with it. Also amends f5140d62082e9b06e0ca6c8e2175b5836286f52e: that looked rather CPU-intensive to call several mapping functions. The test is retained.
