What an important find...
I found out that I forgot to patch a Mouse.getX() and a Mouse.getY() in the EntityRenderer. And looking at it, I never did that in the alpha version either, so this has been broken since the beginning.

This needs a bit of a rewrite in VirtualInput as I never expected something like this. Hopefully not a huge rewrite, but since it's a core functionality, this should also be addressed before publishing a version
