Great! Can you tell me more about your project's needs?

I haven't clearly laid it out, but here's a few items:

* Use GraphicsContext, to support full alpha blending.

* Maybe a layers system

* A re-factoring of the hit-testing/event binding code

* re-factoring of the projection system

* A way to accommodate different scales for x and y axis -- you can do 
this now with a projection function, but it's not very flexible.

* A way to define scale, for printing ans what-not.

* better ways to graphically edit objects (this doesn't really need a 
re-factoring, but it's work to do.

* A document model to put the canvas on , and support saving, etc.

* Maybe make use of Enthought Traits.

* maybe a "tags" system like the TK Canvas, though I'm not that sure how 
useful that really is.

* Lot's of little stuff -- see the ToDo.txt file in FloatCanvas SVN.

Let's take this discussion to the floatcanvas list:
