[Qgis-developer] Rule based renderer can't rotate symbols based on rotation field

 Hi Leyan,

 I am also using the current master.

 If am using the "categorized" or "simple" or "" renderer, there is a 
 "Advanced" button in the bottom right where one can choose a rotation or 
 scale attribute. This button and choice is not available with the 
 rule-based renderer.

 You are right - I can use the ellipse renderer with the rule based 
 renderer, but I would also need it for simple symbols and SVG symbols 
 and for those, we cannot have data-defined settings.

 So it seems that the symbology system is not yet consistent and
