// Here is how the error logging system works.
//
// To catch exceptions that occur in secondary threads, CatchAllExceptions is
// set as the UnhandledExceptionFilter for this process. It records the state
// of the thread at the time of the crash using CreateCrashLog and then queues
// an APC on the primary thread. When the APC executes, it raises a software
// exception that gets caught by the __try/__except block in WinMain.
// I_GetEvent calls SleepEx to put the primary thread in a waitable state
// periodically so that the APC has a chance to execute.
//
// Exceptions on the primary thread are caught by the __try/__except block in
// WinMain. Not only does it record the crash information, it also shuts
// everything down and displays a dialog with the information present. If a
// console log is being produced, the information will also be appended to it.
//
// If a debugger is running, CatchAllExceptions never executes, so secondary
// thread exceptions will always be caught by the debugger. For the primary
// thread, IsDebuggerPresent is called to determine if a debugger is present.
// Note that this function is not present on Windows 95, so we cannot
// statically link to it.
//
// To make this work with MinGW, you will need to use inline assembly
// because GCC offers no native support for Windows' SEH.
