createTextureGpuWindow()

TextureGpu* Ogre::D3D11TextureGpuManager::createTextureGpuWindow	(	bool	fromFlipModeSwapchain,

Creates a special D3D11TextureGpuWindow pointer, to be used by Ogre::Window.

The pointer can be freed by a regular OGRE_DELETE. We do not track this pointer. If caller doesn't delete it, it will leak.
