Don't draw objects with negative x/y values. Now, "ghost" objects are no longer created in the top left corner of the screen when picked up/used. The creation of such ghost objects is a script bug which exists in the original interpreter of IHNM as well. Also, removed a relevant workaround for the note in the first screen of Gorrister's chapter, as it's no longer needed
