/*
 * Structure holding the "global" variables.  Creating a structure with
 * has several advantages over separately declaring each field as a
 * global:
 *  1.  Keep source files clean.
 *  2.  Eliminates need for many "extern" declarations.
 *  3.  A single pointer to this structure can be passed throughout
 *      the application, hiding the fact that it's global.
 *  4.  Allows the variables to be allocated dynamically or from
 *      different memory than the application's DS.
 *  5.  Any reference to these variables will have a pointer or
 *      structure dereference, which points to where the variable
 *      actually is defined.  Separate globals are not distinguishable
 *      from locals, making code harder to read.
 *
 * Note that fNoDirty is used from OLEOBJ.C in the ObjShow method
 * to prevent setting fDirty when the window is sized from ObjShow.
