DRASCULA: Fix random crash when loading pendulum scene savegame

When saving from the pendulum scene the curX and curY values are
negative while the curWidth and curHeight values are unset. This
causes random crashes as we may do an array out of bound access
when enterRoom() is called at the end of the load.
