New in Cuis 3.1
-------------------
    * Super fast Morphic world display.
          o     About ten times faster when many windows are open.
          o     Makes the whole UI feel much more responsive.
          o     Simpler code.

    * New Layout engine.
          o     New layout adjusters and window resizers.
          o     Allows adding / removing morphs without leaving "holes".
          o     Orders of magnitude simpler. Can be understood by humans. Removed all traces of the old code.

    * Cleaner look for Default theme. Nicer buttons, menus and halos. Faster world redraw allows for full-window resize.

    * Morphic buttons simplification: reduced 5 morphic button classes into just one.

    * New Transcript
          o     Fast (Calls return quickly)
          o     Fast (Updates are immediate)
          o     Thread safe
          o     Can log to file in addition to Display
          o     Display output is optional (for headless images)
          o     Can work on a bare bones image (Doesn't need UI, dependency, events, processes)
          o     Optional morphic window for seamless integration in Morphic
          o     UI framework agnostic. Can be used to debug Morphic, even with the morphic window open, without crashing the image!
          o     No longer a text editor. Display is read only.

    * Support for .mcz files (they are treated as .cs and .st files)

    * Removed the colored mouse button naming from all over the system. Now they are #mouseButton1, #mouseButton2 and #mouseButton3.

    * Cleaner Clipboard design & api, to enable extended clipboard

    * Fixes to transparent pixels in 32bpp Forms

    * Lots of code simplifications all over the system: Text, Menus, Tools layout construction, SystemWindow. Killed FakeClassPool.

    * Utilities: #printStack:, better comment at Object>>#is:

    * Many updates from Squeak, including cascading of optimized sends

New in Cuis 2.0
-------------------
Full Closure Support. With full closure support, you can finally use recursive blocks like here:
	fac := [ :n | n > 1 ifTrue:  n * (fac value: n-1)] ifFalse: [1]].
	fac value: 5. "120"
and close over temps correctly, such as here:
	(1 to: 10) do: [ :i | WorldState addDeferredUIMessage: [ Transcript cr; show: i ]].
This is nother closures example
	fib := [ :n | n < 2 ifTrue: [1] ifFalse: [(fib value: n-1) + (fib value: n-2)]].
	fib value: 10. "89"
Cuis 2.0 is ready to run on the Cog VM (when available) and it requires a closures-enabled VM.
