Subject: [PATCH] Filter out resize events if invisible

When splitPane becomes hidden its offsetWidth and offsetHeight is set to zero. This triggers resize handler. Then it calculates maxFirstComponentWidth as a difference between zero offsetWidth and other values, which produces and passes negative "left" value into setLeft. As a result the whole panel shifts beyond the screen after becoming visible again.
