Does anybody know what the theme parts WP_FRAMELEFT
, WP_SMALLFRAMERIGHT
etc are used for? Google doesn't deliver anything useful. I had a look with Windows XP Theme Explorer at them and they look like the caption of dock panels.
Edit: I forgot to mention that I also searched MSDN and got only one result (Parts and States) which isn't exactly verbose about the meaning of the various constants (and announces itself as preliminary).
