I’ll start working on it, but it’ll be pointless (pointer-less?) unless I can figure out why the settings aren’t taking effect for tooltip frames.

I’ve checked this in, and some of the other optimizations I’ve been working on.  That still leaves us calling XSync a bit more than necessary, but I need to work on the error-trapping changes a bit more before I’m happy with them.  Still, this should be a good improvement over the previous remote performance.
