comment padded boundary of convex hull
@Raim I just came across exactly the same problem: it seems that the atan2 function has changed, so you need to switch the arguments: e.g. atan2(\x1,\y1) becomes atan2(\y1,\x1)

comment How to draw a shaded sphere?
You only need to modify the last few lines to change the colour: at the comment %% matte-ify there is 1 number (between 0 and 1) in the stack: you need 3 (being the RGB values). Try playing around with the lines below this point and see how you go (if you get stuck, you can always ask another question...)

It seems that circles just use the centre 50bp x 50bp rendering. So if you make the bounding box larger in all dimensions, it won't change. However if you also change the 25 div to 50 div you end up with a zoomed in version.

ImageMagick didn't like it too much either. Mac preview handled it fine though.

I have found that passing it through eps2eps utility can also help as well.

To make it slightly more general, you can also use \hspace{\beamer@leftmargin}

that works (as long as it is not followed by any non-%ed line breaks). Do you want to make it an answer?

No, you can assume the hull is known, and that the nodes are given in a clockwise direction.
