##### face Gaussian curvature

The [_Gaussian curvature_](https://en.wikipedia.org/wiki/Gaussian_curvature) $K$ at a face, defined via the rescaled angle defect in the face $K_f = \pi - \sum \tilde{\theta}_i$, where $\tilde{\theta}_i$ are the _rescaled_ corner angles (as in `cornerScaledAngles`) incident on the face.
The [_Gaussian curvature_](https://en.wikipedia.org/wiki/Gaussian_curvature) $K$ at a face, defined via the rescaled angle defect in the face $K_f = -\pi + \sum \tilde{\theta}_i$, where $\tilde{\theta}_i$ are the _rescaled_ corner angles (as in `cornerScaledAngles`) incident on the face.

Should be interpreted as an _integrated_ Gaussian curvature, giving the total curvature inside of the face. A corresponding curvature-per-unit-area can be computed by dividing by the area of the face.
