Filtering Steep Faces

The steep slope filtering functionality enables steep faces to be removed automatically during content processing.

This is useful when it is desirable for steep slopes to obstruct agent movement, and enables slope changes to surfaces specified by content to be automatically taken into account during content processing.

This functionality is off by default and can be turned on by passing a 'filterFacesWithSlopeAbove' attribute into the content processing.
This attribute both turns on filtering and supplies a threshold slope value.

The slope threshold is a ratio in the form of vertical distance travelled / horizontal distance travelled.
