/*
This is a truly heinous fix for an awful problem.
The problem: FP2 content has an onMouseDown handler
that says, "if you clicked somewhere other than
what I think the currently-focused component is,
call Selection.setFocus(null)". This is bad because
calling Selection.setFocus(null) tends to completely
confuse the v2 FocusManager,with the net result being
that we end up "dropping" a mousedown event when FP2
content is embedded inside something that uses v2 components.
This "workaround" (actually, "hack") actually dives in
to the content (which we ASSUME TO BE FLASHPAPER)) and
actually replaces the offending onMouseDown handler with a
less-harmful one.

Yes, this is incredibly evil, but an expedient solution
given the nature and timing of the problem.

So that the problem may be fixed in a future version of
FlashPaper, we check for the (currently nonexistent)
member property of "hasSafeSelectionManagement" in the
FlashPaper.MainView class, and only apply this patch if
said member doesn't exist. If we improve FP2's focus
management in the future, we will define this member so
that this patch does not get applied. */
