Well, the solution I came up with isn't great, but it does work. You'll
need to copy PieSeries.as, PieSeriesItem.as and WedgeItemRenderer.as into
your own project and rename them. I named them FullPieSeries.as,
FullPieSeriesItem.as and FullWedgeItemRenderer.as. Easiest thing to do is
put them all in the same package so they can find each other, avoiding
imports. I'm going to assume you do that. If not, you'll need to fix your
imports.
Unfortunately, since the charting classes are part of the Pro version, I
don't think I can just post attachments of the new files here. If someone
from Adobe wants to give an okay, I will.
Otherwise, we'll just have to go step-by-step.

Hopefully, I didn't leave anything out. If this doesn't work, let me know.
Now, you may notice something. The FullPieSeries is set up to handle having
no drop shadow by default, using the FullWedgeItemRenderer renderer. But if
you wanted, you could set the filter back to a drop shadow and set the item
renderer to WedgeItemRenderer. You'd then get a drop shadow, even with
FullPieSeries. But if you don't change anything else and just use
FullPieSeries, the pie will go all the way to the sides.
Hope this helps!
