// modal dialog controller
// handles a stack of dialog elements
// each element can have one of the following states:
//   0: hidden (fading out)
//   1: visible (zooming in)
//   2: greyed out (inactive)
// While an animation is running, no item has focus. When an animation is done,
// the topmost item gets focus.
// The items are assumed to be added in overlapping order, that is, the lowest
// window must get added first.
//
// Possible uses:
// - to control a modal dialog:
//   - show modal dialog: me.showChild(me, childItem, buttonAbsOrigin, buttonAbsSize, 0) // childItem also gets focus
//   - dismiss modal dialog: me.hideChild(me, childItem, 0) // childItem fades out and relinquishes focus
//   - show first screen in m_show: me.hideAll(me, 1); me.showChild(me, me.firstChild, '0 0 0', '0 0 0', 1);
// - to show a temporary dialog instead of the menu (teamselect): me.hideAll(me, 1); me.showChild(me, teamSelectDialog, '0 0 0', '0 0 0', 1);
// - as a tabbed dialog control:
//   - to initialize: me.hideAll(me, 1); me.showChild(me, me.firstChild, '0 0 0', '0 0 0', 1);
//   - to show a tab: me.hideChild(me, currentTab, 0); me.showChild(me, newTab, buttonAbsOrigin, buttonAbsSize, 0);
