SVG Urgent Tasks

Dear all, We have couple of tasks: 1. We are generating SVG via PHP code and we need functionality for zooming and panning of dynamically generated SVG. 2. We also need to find SVG Path. We need to find SVG Path's central point. Even if you don't have the code thats okay; just the formula or the algorithm for finding SVG Path's central point would be fine. You can bid on both or either of the above two tasks. This task needs to be done AS SOON AS POSSIBLE. Bonus, great review and hopefully more work for the successful guy. Please make a bid and DO sent a private message and start it by saying 'green'. Thanks and good luck
