WINDOWS
Summary:
A handle is a unique, fixed identifier for a global object. Handles
exist to allow easy, indirect access to an object that may move in
memory.
Handles are unique only among the objects to which they refer. A
handle to a window will always be different from all other handles to
windows, but it could have the same value as a handle to a brush (or
to any other object).
It is safe to hold onto a window handle (or any handle) of a global
object. As long as that object exists, its handle will not change.
