[Ann] MorphicDraw

To better understand Morphic, I've started writing a small application
that can draw shapes and connect them.

A pdf documenting what I've done is at
https://github.com/StephanEggermont/MorphicDraw

Code is on smalltalkhub,
StephanEggermont/MorphicDraw

Suggestions, fixes and improvements are welcome

I have not yet read it, but this is very cool, well done !

This kind of material is very welcome.

Thanks.

I am pleasantly surprised by the small amount of code needed
to create something like this. Not so much by the effort in
finding out how to do these things. I found it necessary to
look in a Squeak image to see how other Morphs/Morphic
applications dealt with events, especially when tracking the
hand.

There are a few things that I've not yet solved:
- I've added #isMorphicDraw and #isMorphicDrawShape to make sure
   only MorphicDraw shapes don't escape from their panel, and
   no other morphs are added to the panel. Is there a more
   elegant way to achieve that?
- In MDCard I've added TextMorphs to the shape. They don't
   like right clicks. MNU TextMorph>>editView.
- How do I tell a PolygonMorph to use bezier curves with
   a starting direction for the end points?

Double-dispatch?
