slideshow\glTF: add a parent window to the OpenGL window

OpenGL window is a SystemChildWindow which doesn't handle
window events as a vcl Window does (call it's event
handler functions and the given event listeners), so
I added a new parent which will handle window events
and capture them from the slideshow's main window.
