Feature Request: QMdiArea bring multiple windows to foreground

It would be useful if a QMdiArea::bringToForeground(QList<QMdiSubWindow*> function was added, where the order of the QList could represent the stacking order.

This could be useful for example when having a QMdiArea with multiple subwindows where those subwindows are grouped by documents that contain their state. For example, 4 subwindows could be showing data from document 1 and another 2 subwindows could be showing information from document 2. When selecting document 1 (e.g., via some toolbar button), all the related QMdiSubWindows should be put in the foreground. It would be nice to have a QMdiArea::bringToForeground(QList<QMdiSubWindow*>) that could handle this, with the order of the QList representing the stacking order.
