I think before giving up we should ask some browser folks actually well versed in their layout/rendering implementations to chime in and tell us whether what we're trying to accomplish is more or less viable, and/or if there's a better approach to achieve the same goals. Also, since the protection is opt-in, *maybe* a trade of between rendering performance and security would be acceptable, if properly documented. As a start I'm CCing Robert O' Callahan, who IIRC works or used to work on Mozilla's gfx internals: could you please take a look at https://dvcs.w3.org/hg/user-interface-safety/raw-file/43644c06b379/user-interface-safety.html#alt_heuristic ? Any comments/suggestions? Many thanks in advance! Also if you know any other field expert from Mozilla/Google/Apple/Microsoft who may want to help, please let us know.
