 ============================================================================== = 
                                Popup plugin
Plugin Name: Popup
Plugin authors: Luca Santarelli aka hrk (hrk@users.sourceforge.net)
                Victor Pavlychko aka zazoo (nullbie@gmail.com)
 ============================================================================== = 
The purpose of this plugin is to give developers a common "platform/interface"
to show Popups. It is born from the source code of NewStatusNotify, another
plugin I've made.

Remember that users *must* have this plugin enabled, or they won't get any
popup. Write this in the requirements, do whatever you wish ;-)... but tell
them!

Otherwise, it can return anything else...

You may pass additional creation flags via lParam:
	APF_RETURN_HWND ....... function returns handle to newly created popup window (however this calls are a bit slower)
	APF_CUSTOM_POPUP ...... new popup is created in hidden state and doesn't obey to popup queue rules.

/* Popup/UnhookEventAsync
Using of "UnhookEvent" inside PluginWindowProc in conjunction with HookEventMessage
may cause deadlocks. Use this service instead. It will queue event unhook into main
thread and notify you when everything has finished.

Deadlock scenario:
1. Event is fired with NotifyEventHooks in the main thread
2. Miranda core calls EnterCriticalSection(csHooks) and starts notifications
3. You decide to unhook event, therefore call UnhookEvent
4. Miranda core *INSIDE YOUR THREAD* calls EnterCriticalSection(csHooks) and
waits for main thread to finish processing
5. Main thread calls SendMessage(hwnd, ...) to notify your window
6. Your window's thread is busy waiting for main thread to leave critical section
7. deadlock....
