Arguments: window &key include-ancestors
Returns a plist that indicates whether each capability of the gesture
interface is enabled for the specified window. Each key in the plist
is a keyword symbol that corresponds to one of the arguments to
configure-gestures. Each
value is either t if the capability has been
explicitly enabled by a call to configure-gestures, nil
if it has been explicitly disabled, or :inherit if
the value is inherited from an ancestor window or else from system
defaults.
If include-ancestors is true, then
Microsoft says that it "returns consolidated configuration for the
specified window and its parent window chain". This appears to mean
that if :inherit would otherwise be returned for a
value, but there is an ancestor window for which the capability has
been explitly enabled or disabled, then t or
nil is returned to indicate the inherited
behavior. But :inherit will still be returned if
the unknown system default is inherited.
