Hi all, I'm re-sending this to the list to put it at the top of peoples inboxes. Please do review mail below before our discussion later on the APA call. My suggestion to the group is that there may be an issue when rendering/re-rendering of certain content at different resolutions. My reading of the spec is that we need to make sure any accessibility related content/alternatives do not suffer interpolation or aliasing issues when re-rendering. Happy to discuss later.
