[cp-patches] FYI: Made some components opaque

[Roman Kennke]

I noticed that several components that should be opaque (they are in the
JDK), are not flagged as beeing opaque in Classpath. I fixed this with
the attached patch. At the moment this only affects the drawing in that
the opaque flag decides if the ComponentUI draws the components
background or not. I am working on an improved RepaintManager that also
uses the opaque flag to optimize drawing. It would not be necessary to
step back up to the RootPane and draw everything if the opaque property
is correctly respected.
