[7u6] Review request for 7142091: [macosx] RFE: Refactoring of peer initialization/disposing

[Sergey Bylokhov]

Hi Everyone,
Please review the fix.

Notes from the bug and comments:
1. setVisible() should be called at the end of the peers initialization. 
We can move super.initialize() to the end of the peers initializations.
Initialize() was split to initialize() and initializeImpl(). In the 
initialize() we call initializeImpl and then we call to setVisible(). 
initializeImpl overridden in subclasses.

2. Invokelater in the initialization/disposing is a tricky.
Removed.

3. replaceSurfacedata() should be moved outside of 
LWWindowPeer.setVisible()
Done. Also duplicate code was extracted to setVisible() method which 
call setVisibleImpl().

4. Backbuffer in replaceSurfacedata() should be initialized by clearRect 
instead of fillrect(composite is important).
Done. related to composite.

5. During lwwindowpeer initialization we call two similar methods 
nativeSetNSWindowAlpha() and setAlphaValue().
nativeSetNSWindowAlpha() removed from CPlatformWindow.java.
