[Gimp-developer] Path stroking mysteries

[Ofnuts <ofnuts laposte net>]

- Make an ellipse selection
- Stroke the selection with a 2px solid line, and anti-aliasing checked 
in the Stroke dialog: the line is jagged (at least on my Linux 2.6.8 and 
2.7.2, and on a Windows 2.8)
- "Select/To path" and stroke the path with the same stroke parameters: 
the produced line is smooth.

Conversely, make a path, stroke it: the line is smooth. Create a 
selection from the path and stroke it: it is jagged.

That could be a bug (but I didn't find anything like this on bugzilla), 
but it has been around for so long that it could be a feature, and if 
so, what is the rationale?

Btw, I also looked for a PDB entry to stroke a solid line on a path and 
couldn't find any.: gimp-edit-stroke and gimp-edit-stroke-vectors use 
the active brush and this doesn't give the same squeaky clean results as 
stroking with a solid line. Did I overlook something? Otherwise, is 
there an explanation for the missing function? Oversight? Lack of 
demand? Lack of time? Deemed not useful?
