// notes:
// - FOS_SUPPORTSTREAMABLEITEMS doesn't seem to be supported on windows vista, or at least not with the flags we use
// - even with FOS_NOVALIDATE the dialogs will reject invalid filenames (at least on Vista, anyway)
// TODO
// - http://blogs.msdn.com/b/wpfsdk/archive/2006/10/26/uncommon-dialogs--font-chooser-and-color-picker-dialogs.aspx
// - when a dialog is active, tab navigation in other windows stops working
// - when adding uiOpenFolder(), use IFileDialog as well - https://msdn.microsoft.com/en-us/library/windows/desktop/bb762115%28v=vs.85%29.aspx
