60153: Handle Plain Decoration
Handler for the object types 116 to 120: the clock, the tapestry, the table, the sideboard and the bird (see Sprite_Clock_1). These decorations are drawn in the single attribute of the record, which is cyan. The other decorations, which have colours of their own, are handled by Handle_Coloured_Decoration.
A decoration is removed (see Handle_Collectable_Remove) when Sabreman is not in its room. The first time that it is handled Set_Decoration_Size gives it the size of its obstacle, which Check_Object_Contact uses to find out if an object touches it, and then Handle_Static_Object draws it. After that Handle_Static_Object only colours it.
