SIrrlichtCreationParameters::IgnoreInput set to false works again on X11.

Browse Source 
Thanks @ Victor Gaydov for report + patch + very good test cases! (bug #401)
This had been broken since Irrlicht 1.6
The reason was that Irrlicht 1.6 wanted to ensure Irrlicht renders to given parent window instead of creating a child window in the parent window. That still works, but only with SIrrlichtCreationParameters::IgnoreInput set to true.
Added a few comments about further improvements as rendering to the given parent Window is likely also possible for this case, but that will need more work.
