 ===============================================================================
                                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!

NOTE! Since Popup 1.0.1.2 there is a main meun group called "PopUps" where I
have put a "Enable/Disable" item. You can add your own "enable/disable" items
by adding these lines before you call MS_CLIST_ADDMAINMENUITEM:
mi.pszPopUpName = Translate("PopUps");
mi.position = 0; //You don't need it and it's better if you put it to zero.

/* PopUp/AddPopup
Creates, adds and shows a popup, given a (valid) POPUPDATA structure pointer.

wParam = (WPARAM)(*POPUPDATA)PopUpDataAddress
lParam = 0

Returns: > 0 on success, 0 if creation went bad, -1 if the PopUpData contained unacceptable values.
NOTE: it returns -1 if the PopUpData was not valid, if there were already too many popups, if the module was disabled.
Otherwise, it can return anything else...

Popup Plus 2.0.4.0+
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.
							you may control it via UM_* messages and custom window procedure
