The demo works just fine now!

I was hoping you did!

1.Once you have a NBOpenGLRomeCanvas , how do you plan to implement the zoomable UI? On which layer of abstraction? (Canvas or  Morphic ?)
Is there going to be a "camera" abstraction? ( just like Lumiere ) or who will know  its current z transformation?

2. Regarding Text, will you reuse Paragraph and Editor already present in the system, or use an external library like Pango?
 I was looking at the True Type font rendering demo, and everything seems pretty much into place, and now the "paragraph" layer must be implemented.

How can i help? (Eventually...)
