[Etoys] Drawing with the mouse.

Drawing with the mouse.

Note: This somehow got delivered in two pieces.
Here it is pieced back together again.  -Jer

The gui problem is that it is hard to draw good lines with a mouse.

The cursor becomes a lot more managable for drawing
when it slowly moves the pen tip.
That is, the amount of motion to move the pen a little bit
must be larger for drawing than for pointing.
If you miss while pointing that's no big deal you correct and get there.
With drawing you want control as you draw
so the pen object needs to move much slower than the cursor.

This is not too hard (for a developer) to do.
