Mostly delicious, Corinna.

The hard edges in the original art are causing stair-stepping when doing 
a direct downsample, though.  (Look at the pointy bits.)  By blurring 
the high-res version and then downsampling by a non-integral amount, you 
can get a much smoother result.  Here's one at 128 px^2:

If you're really set on 152 px^2, here's that, too:

If you want yet a different size, the procedure is:

	- merge all layers (don't flatten; keep transparency)
	- Gaussian blur, 2 px
	- bilinear resize
