I'm not sure we were all talking about the same thing here. Scaling the whole shadow is a very different (and to me, vastly less important) from spread (which is really an outward or inward offset). But I am not at all apposed to offsetting the straight parts and then scaling the corners, as this is very, very close to achieving the same effect (maybe even a little better, as I confirmed in follow-up tests).

Also, as for GPU acceleration, I am not that familiar, but I think this could be done as a raster effect which might allow GPU acceleration. We had talked about it a little when we were considering drop shadows for border-images, way back when. In Photoshop there is a filter called "minimize" that does something similar (it reduces the white area by expanding the black area, sort of). But the corners are not kept sharp. Would something like that be better (if we can live without the sharp corners requirement)?
