This fixes some slowdowns in Kyra2 with the OpenGL backend for me. Most of the updateScreen calls saved were introduced by us implementing the original behavior of hiding the mouse before drawing onto the screen and showing it again afterwards, since the mouse cursor is not drawn on the game screen in our implementation (and unlike in the original) this is not necessary.
