Details

In example surface_plot_edge.cpp we had a surface plot with a large, undefined region easily discovered by Maple & Nathematica. In this example we have a surface with a smaller, annular undefined region that is harder for automatic software to get right. The function in question is as follows:

\[ \sqrt{\sqrt{\vert 1 - x^2 - y^2\vert} - \frac{3}{20}} \]

This example differs from surface_plot_edge.cpp in that we direct additional sampling near the unit circle. Other than that, it's just about identical.
