(svn r7205) -Fix [FS#350, SF#1560913]: Window allocation and deletion messed with the actual window

Browse Source 
structs inside their array, and possibly invalidating pointers higher up.
 Meaning that any function called within an wndproc could cause unknown/invalid pointers
 once control was returned to this function. Solved by the introduction of an extra
 abstraction layer, an array of z-window positions that is only concerned with the
 pointers.
