[Dojo-interest] How to destroy a shape but not all shapes on a surface?

[Jamey Graham]

re: 1 - i believe you need to describe the new shape attrs w/ setShape() [vs. dojo.attr].  i.e. imgShape.setShape({src: newSrc})).  NOTE that under the covers (and perhaps needing to be documented) setShape() calls makeParameters() which I believe functions similar to setShape(dojo.mixin(getShape(), updatedAttrs)) [i.e. you only need to pass in the attrs that are changing...]  

re: 2 - there's Shape.removeShape(false) or Surface.remove(shape) [although i'm not sure how all renderers handle cleanup]
