Radial gradient split failure with EdgedFace

(Hard, this is the bug I was describing with the circular clipping where we're getting a mismatch of edges).

It seems like EdgedFace.getBinaryCircularClip is outputting invalid data. As discussed, later stages need the start/end points of edges to match up precisely. I probably screwed up something like this in CircularClipping.binaryCircularClipEdges.

To reproduce, apply the patch below (or just... enable the one test in RasterizeTests.ts), and run the unit tests.
