// Description:
// TVIEW2
// Tests integration of view architecture throughout the ViewSrv, Cone, Apparc, Uikon and RefUI layers.
// Tests basic view switching and appUi embedding. Tests various exceptional view switch conditions
// including OOM during activation, attempts to start missing apps, tests panics while idle, while
// activating and while deactivating and very slow activations and deactivations.
// Should be used with companion test app TVIEW1 - the target view for each test view switch is in this app
// and using TVIEW1 means that the test view switches can be initiated from a different thread.
// TVIEW2 can be used for stress testing the view arc by setting up queues of events while doing
// the longer tests and killing random apps etc.
// If TVIEW1 is running when TVIEW2 is started TVIEW1 will be set as the owning window group
//
