PDBHandler is an extension to enable interactive 3D models using WebGL, intended for Wikipedia deployment. I've got it working with MediaWiki 1.21 and would like to have the code reviewed. It's had a design review; the current implementation reflects comments from that.
Test deployment: http://pdbhandler.wmflabs.org

(Some initial review comments have been made, but I thought it'd make sense to also track the review status here.)
