[Cuis-dev] Mouse Event

[Juan Vuletich]

Hi Hilaire,

Most likely, the drawing of your PaperMorph takes too much time. The 
alternatives I see are either find ways to speed it up, or decouple the 
capture of the samples from the drawing, and, for example, only update 
the morph on buttonUp. That would require a different way to give the 
user feedback about the samples that are being taken.

Hope this helps,
