// to do it with the features I want. It's a good exercise to start
// thinking on how to do this to convince your self that all this
// is really needed for the general case.
//
// The algorithm two draw 3D pies without "real 3D" is done in
// two steps.
// First imagine the pie cut in half through a thought line between
// 12'a clock and 6'a clock. It now easy to imagine that we can plot
// the individual slices for each half by starting with the topmost
// pie slice and continue down to 6'a clock.
//
// In the algortithm this is done in three principal steps
// Step 1. Do the knife cut to ensure by splitting slices that extends
// over the cut line. This is done by splitting the original slices into
// upto 3 subslices.
// Step 2. Find the top slice for each half
// Step 3. Draw the slices from top to bottom
//
// The thing that slightly complicates this scheme with all the
// angle comparisons below is that we can have an arbitrary start
// angle so we must take into account the different equivalence classes.
// For the same reason we must walk through the angle array in a
// modulo fashion.
//
// Limitations of algorithm:
// * A small exploded slice which crosses the 270 degree point
// will get slightly nagged close to the center due to the fact that
// we print the slices in Z-order and that the slice left part
// get printed first and might get slightly nagged by a larger
// slice on the right side just before the right part of the small
// slice. Not a major problem though.
