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