Bug 935: NEWT OSX PointerIcon/Pointer-Visibility: Impl. OffscreenLayerSurface (OSX CALayer) w/ JAWTWindow Path

Add setCursor(..) and hideCursor() to OffscreenLayerSurface interface,
impl. in JAWTWindow w/ AWT.

This allows an OSX NEWT Window using CALayer (i.e. NewtCanvasAWT)
to have setPointerIcon(..) and setPointerVisible(..) functionality!
