another thread to createWindow

For help with anything that CEGUI doesn't offer straight out-of-the-box, e.g.:
- Implementation of new features, such as new Core classes, widgets, WindowRenderers, etc. ...
- Modification of any existing features for specific purposes
- Integration of CEGUI in new engines or frameworks and writing of new plugins (Renderer, Parser, ...) or modules

DWORD WINAPI ProcessThread(LPVOID params)
{
....
ProcessPackage(...);
}


ProcessPackage(...)
{
//when in here invoke createWindow method the programe is crash!!!!
WindowManager& winMgr = WindowManager::getSingleton();

Window* frame = winMgr.getWindow("Demo/Window");

Window* button = winMgr.createWindow("OgreTray/Button","test");

button->setSize(UVector2(cegui_absdim(50),cegui_absdim(50)));
button->setPosition(
UVector2(cegui_absdim(150),cegui_absdim(150)));
button->setProperty("Text", tagList->RoomVector[i].RoomName);
frame->addChildWindow(button);
}

CEGUI is not thread safe, you have to use synchronisation primitives and/or queues to make this work.

whatever you render platform base on DirectX or OpenGL or Opengl ES ,
these are support multi render content to make multi thread Render devices work.
I get this same problem when use cegui in IOS platform { Opengl ES 1.1 }, then to create multi render content for easy render thread to solove this problem.

sorry for my English , I'm Chinese.
