first i want to implement morphic rendering pipeline which will use
Rome canvas, instead of Canvas.
Next, i want to replace PasteUpMorph (World) with own subclass, which
will actually control the camera, zoom level etc.
So, it will be a global desktop-level zoom&translation. A submorphs
will be not aware of it.
In this way, its a less work and less changes to existing Morphic (i hope).
And of course, i want a clear separate layer (Rome canvas) which can
be used by any other UI/graphics framework.

Initially, i will just do the simplest possible thing. Reuse what
Text/paragraph rendering is a separate and very complex problem. Of
course it would be cool to do things right,
but not at initial iteration :)

Anything you want. If you want something to be there, don't hesitate
and dont wait for me - start coding :)
My projects are public, they are open for contributions from anyone.
Also, it would be cool to sync with Juan and his work on Morphic 3.
I'd like to provide a GL backend for Morphic 3.
But its unclear to me, what plans Juans having about it. Recently he
said that he won't make any public releases.
But i really hope that we could work together on it, because such
ambitious projects need more than a single man
in order to complete.
