scummvm/sword2/controls.cpp
Torbjörn Andersson fc970b3c75 Removed the buffering of mouse and keyboard events. I don't think any of 
our other engines do this, so there is little reason for BS2 to. I did add
a filtering mechanism so that mouse button releases and scroll wheeling is
ignored during normal gameplay, but I don't know if that was necessary
either.

Since this left little more than an empty husk where the Input class used
to be, I've eliminated that class and buried its remains in Sword2Engine.
