Hi Juan,

Here is a small change set over your recent TextParagraphMorph to add 
background and border by inheriting from WidgetMorph.

I want to use this morph has a status bar information widget in DrGeo 

There is still an issue I can't fix: the text is drawn over the border, 
not sure there is an elegant way to solve it without redrawing the 
border, which ruin the inheritance. It is a bit like 
#textComposition:bounds:color:selectionColor: is not strickly honoring 
the bounds argument.

I let check out. I have another change of the drawnOn: method but you 
may have better idea
