// As discussed in change 7072, QDialogs have different minimize and "on
// top" behaviors depending on their parents, flags, and platforms.
//
// W = Windows, L = Linux (and other non-macOS UN*Xes), X = macOS
//
// QDialog(parent)
//
//   W,L: Always on top, no minimize button.
//   X: Independent, no minimize button.
//
// QDialog(parent, Qt::Window)
//
//   W: Always on top, minimize button. Minimizes to a small title bar
//      attached to the taskbar and not the taskbar itself. (The GTK+
//      UI used to do this.)
//   L: Always on top, minimize button.
//   X: Independent, minimize button.
//
// QDialog(NULL)
//
//   W, L, X: Independent, no minimize button.
//
// QDialog(NULL, Qt::Window)
//
//   W, L, X: Independent, minimize button.
//
// Additionally, maximized, parent-less dialogs can close to a black screen
// on macOS: https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=12544
//
// Pass in the parent on macOS and NULL elsewhere so that we have an
// independent window that un-maximizes correctly.
