I made all the extra variants needed for the topic index ones Prox made. The poll ones are the same though. I'm not sure how to give them all the extra properties they'd need.
For example, each icon needs Normal, Sticky, Locked, Sticky + Locked versions. Then it needs versions of each of those to denote the topics you've posted in (which we used bubbles to indicate on the normal post icons). Then you need variants of all of those for normal, hot, and very hot topics. So that's 24 different images for the post icons, which are done, and another 24 needed for the poll ones. But there's no room on the poll one for cracks to show lockedness or bubbles to show if you've posted in it, so I'm not sure what to do with'em yet.
