[Inkscape-devel] a idea

hi, I am not a developer yet, I am a student of informatics engineering, now, I have a idea to do shadows, using the border attribute of objects, in theory use a parallel degrade, started in the inside part of the border, and go to transparent at the end of border for shadow to out and reverse to shadow in. this is my idea (I don't speak English well), I will develop this option someday and bring it to you, now I bring you only a idea, if somebody developed this thing, tell me please, bye,

PD:this shadow is something like the shadows of gimp or fireworks, this kind of shadows give realism to a image in svg
