[Cuis-dev] Cuis Morphic question

[Gastón Caruso]

Hi, do you think it would be useful to add a comment in the method?

You can think of it extent as the minimum size they require to be displayed without loosing it's meaningful representation. For example, if the morph represents a table with 4 legs and if shrinked past some threshold its legs disappear it stops representing the table it supposes to represent. The minimum extent tries to prevent this. 
> Coming back to your question, an extentBorder that by default returns 0 means that the border of the morph is not part of the essence of the morph. If a morph always requires its borders to be displayed because they are part of what it represents then it should redefine this message with the minimum meaningful extent of the borders.
