When looking at the perspective transform effect I realized it is nothing less than the stuff Adobe presents as 2.5D or "postcards in space" feature of Flash 10. The only difference is in Flash the API is way more user friendly and nicely high-level, whereas out API is quite low-level and does not have the necessary visibility. Therefore I suggest to create a special node in the scene graph (perhaps extending a group), which would allow to easily project the content of that node using perspective transform. The APIs of the node should think rather in x/y/z rotation variables than in the direct mapping we have in the perspective effect.

It would be great to have this ASAP and since all the implementation already exists and we need to just create a nice and usable API around it, it would be awesome to get this to Franca. Nevertheless Marina would work as well.
