SetDoubleClickInfo - Set the double-click rectangle and timeout

Private Declare Function SystemParametersInfo Lib "user32" Alias _
    "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, _

' set new values for the double-click area, and the
' time within which the user must click the mouse button
' again to be considered a double-clicl

' WIDTH and HEIGHT are the size (in pixels) of the rectangle
' inside which the second click must occur - default is 4 pixels
' TIMEOUT is the timeout (in milliseconds) - default is 500 milliseconds.
' If MAKEPERMANENT is True, then these new values persists among
'    subsequent Windows sessions
