asserts are not left in the release code at all.

-This is an event handler function called when the operating system or GUI session is
-about to close down. Typically, an application will try to save unsaved documents
-at this point.
-
-If \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto} returns true, the application
-is allowed to veto the shutdown by calling \helpref{wxCloseEvent::Veto}{wxcloseeventveto}.
-The application might veto the shutdown after prompting for documents to be saved, and the
-user has cancelled the save.
-
-Use the EVT\_QUERY\_END\_SESSION event table macro to handle query end session events.
-
-You should check whether the application is forcing the deletion of the window
-using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is true,
-destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
-If not, it is up to you whether you respond by destroying the window.
-
-The default handler calls \helpref{wxWindow::Close}{wxwindowclose} on the top-level window,
-and vetoes the shutdown if Close returns false. This will be sufficient for many applications.
-
-\wxheading{Remarks}
-
-Under X, OnQueryEndSession is called in response to the `save session' event.
-
-Under Windows, OnQueryEndSession is called in response to the WM\_QUERYENDSESSION message.

This function is called when an unhandled C++ exception occurs inside
\helpref{OnRun()}{wxapponrun} (the exceptions which occur during the program
-startup and shutdown might not be caught at all).

-the exception you should override \helpref{OnRun()}{wxapponrun} and put a
-try/catch clause around the call to the base class version there.

+event loop has been terminated and the program will exit, if you want to
+prevent this from happening (i.e. continue running after catching an exception)

Allows the programmer to specify whether the application will use the best visual
on systems that support several visual on the same display. This is typically the
case under Solaris and IRIX, where the default visual is only 8-bit whereas certain
applications are supposed to run in TrueColour mode.
+If \arg{forceTrueColour} is true then the application will try to force
