Test Tilt

See the attached application that shows the customer observations for different Tilt values.

- 0º: A is clearly not attached to B. (Slice B, by the way, has a negative Height. This seems to cause all sorts of problems for the renderer.

- 30º: Changing the Tilt value rotates the pie chart, but tilts the shadow. And slice D is doing something very strange along the rim of the pie look at the way it bleeds over into section C.

- 40: Between 40 and 41 degrees, the shadow disappears entirely. It doesn't reappear until around 310 degrees.

- 41: Between 40 and 41 degrees, the shadow disappears entirely. It doesn't reappear until around 310 degrees.

- 90: The chart looks very, very strange at 90 degrees. The perspective is completely wrong on segment A (you can see both the inner and the outer curves of the donut) and the inner edge is rendered out of line with the edge of the slice arc.  A is still not connected to B, and its inner curve isn't rendered, although we can see that something is trying to set that up by the way the edge of the slice drops down.  Also, there's a couple of smudges slightly to the right of slice B, one above and one below.

- 180: A and C displaying severe bleed into other segments.

- 270: D gets in on the action, and now C is doing the inner curve glitch thing that A was doing in 90º.  Also, what's that spike beneath section C?

- 315: The shadow beginning to reappear, except it's emerging along a different axis than the one it flattened along 0 to 41º

- 330: The shadow beginning to reappear, except it's emerging along a different axis than the one it flattened along 0 to 41º
