See EglPBufferWindow.

We do not track this pointer. If caller doesn't delete it, it will leak.

◆ createTextureGpuWindow()

Creates a special GL3PlusTextureGpuWindow 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.
