Hi Stef,

Your email made me think a lot.

Actually no, but it is likely that we should. A general way to defines polygons is the way to go.

After having played with Athens, I understand better what you actually mean.
Indeed, the end user should work with a notion of polygon in general, and not with SVG.

You are very very right. We indeed do not want to introduce all these classes.

Your email made me think about something: rewriting Roassal from scratch, but putting the core notions brought by Athens at the center of Roassal. I spend some time on getting the camera working in Roassal, but Athens was not ready yet. More Roassal will use Athens, and more we are taking advantages of the graphic card.

Also, do we have to wait for the text editor to include Athens in Pharo? The text editor is essentially to bootstrap and remove Morphic right? But until then, Athens could be part of Pharo. I am now using the Moose image, which is nicely packaged with proper fonts and Athens. Since there are many users of Roassal on Morphic, it is hard for me to move to 100% Athens.

Thanks again for your email

Alexandre
