Comment(by wonder):

 Hi Mayeul,

 thanks for the patch. I had a brief look at it and I like some parts of it
 :-)

 Personally I think it would be good to separate the patch to "safe" and
 "unsafe" part. Things like support for rule label and description could be
 committed immediately, however the changes related to symbol levels are
 unstable and should be given more time to settle down.

 Regarding the symbol levels, I do not like the approach with merging of
 the symbols. I have in mind some improvements to renderer interface that
 would solve it: instead of calling renderer's symbolForFeature() when
 rendering with symbol levels, the draw() method from QgsVectorLayer would
 let renderer to connect more symbols with a feature. I will try to work on
 this in the following days/weeks.

 In the meanwhile, if you attach a newer version of the patch that leaves
 out the changes regarding symbol levels, I would be happy to apply it in
 case there are no problems.

 Martin
