Proposed: An SVG Scene (aka canvas) Library for Cairo Feedback requested!

Goals

Provide functionality & perfomance suitable for creating full UI/page/etc. Enable multi-client/collaborative applications Enable lightweight applications for mobile platforms Enable presentation of compound documents

Features & Requirements

Implement SVG object model Render to Cairo; any Cairo backend Layout text with Pango (what about flowText?) Support incremental rendering (differences only) Provide model API for insert/delete/update/z-move Support out-of-process API calling, i.e. for compound documents Provide API to identify SVG object & group at xy, i.e. for hit-testing Allow out-of-band regions (non-SVG, non-Cairo), e.g. video/3D Allow higher-level widgets/applets to "own" model objects Allow use in various frameworks GTK/QT/airWRX/Cocoa/.NET/Python/Java Support multiple clients/viewers of a scene on IP network Support client-specific objects, and properties, e.g. text selection

When there's some consensus, I'll crank out a lib for cairo-win32 from our existing code, write a demo app, and release as a prototype under LGPL.

The Inkscape Wiki discusses an SVG-based canvas lib, but it looks far out on their roadmap. Could any Inkscape folks comment?
