And some notes about input.
Again, morphic should not assume that there are standard input devices
, like keyboard and mouse, it's should be able to interact with any
available input devices.
For this, i think, we should think twice on how introduce different
events in future morphic system.

For instance, what is the point in having #handlesMouseDown: ,
#keyDown: methods, when there is no mouse/keyboard on platform (assume
i run squeak on touchpad)?

These layers should be detached from each other, i think, and morphs
should react on more abstract (or generalised) events.
