[Pharo-dev] Rubric #mouseDown, #mouseUp and #click

[Stephan Eggermont]

We have a few morphs where #on:#mouseDown send: aMessage to: aTarget is 
used where I'd expected that to be on #click. Mostly in Rubric and the 
Nautilus annotations

If a morph is supposed to behave as a button, the action should happen
on the #mouseUp, but only if the mouse pointer hasn't moved away from
the morph. That is what #click does.
And
ExpanderTitleMorph
GrowlMorph
JobProgressMorph
react on #mouseUp instead of #click
