This file contains changes that implement a "raw" -smooth method (as described in TIP 168) for canvas items. It also does some cleanup of terminology in comments to specific functions. Affected files are tkTrig.c, tkCanvUtil.c, and tkInt.decls.

Logged In: YES user_id=938835 It lacks the detail of changing the name (as reported by [$canvas itemcget $item -smooth]) of the traditional smoothing method from "bezier" to "true". I wasn't sure how to implement that. One way is to add a special case in TkSmoothPrintProc and still call it "bezier" in the declaration. Another way is to change the declared name to "true" and add a special case for the name "bezier" to TkSmoothParseProc. Related is the matter of how the "raw" method should be registered. The patch _doesn't_ register it, but implements it as a special case in TkSmoothParseProc because I couldn't spot a point where one could make such a registration. There is a comment about this in the patch (last block). IMVHO the least confusing approach is to have a bunch of special cases in TkSmoothParseProc, even though that would be somewhat inelegant.

Logged In: YES user_id=79902 Is this a *complete* implementation of the TIP?
