Ok, I think the problem here is that I sidetracked myself into thinking primarily about rounded corners, when I was most interested in consistent and, preferably, intuitive handling of corners among the various object types. What I've learned is that the various renderers have the concept of a line join _built in_, and that the available ones are mitre, bevel, and round, present in both the Cairo renderers and in the Gdk renderers.
I think that using these will address my concerns; here's the framework I suggest (elaborated from a previous version): 1. Add pulldown "join type" parameter to box, polygon, polyline, zigzagline, and possibly bezierline and beziergon (for when they have cusp rendering). This menu would have values mitre (default), bevel, and round. 2. Remove "corner radius" parameter from polyline, zigzagline, since its use is basically subsumed by rounded joins. 3. Leave "corner radius" in box, where it triggers a rounded rectangle to be drawn instead of a regular rectangle; "join type" is still present but is ignored. Within that framework, two bugs can be fixed: #535871, to do with rounded corners on polyline and zigzagline, automatically goes away since it arises from manually fiddling with arcs. #534275, to do with (lack of) joins on lines and consistency between objects, is likewise fixed. (Part of this may have already been fixed in the SVN trunk even before my report; I don't see a recent change that would have fixed it. Curiously, if I save a file using the SVN version and open it with 0.96.1, the boxes *do* have mitred joins, but then if I double click them and immediately click "apply" they go away!) I've done some proof-of-concept hacking and it looks like the Gdk and Cairo renderers both handle MITER and ROUND beautifully. I've got other stuff tomorrow, but if the above thoughts seem reasonable I'll try to put together a patch on Sunday. -- -=-Don [EMAIL PROTECTED]<http://www.blahedo.org/>-=- Ask five economists and you'll get five different explanations (six if one went to Harvard). --Edgar R.
