Add methods for rasterising filled volumes: arbitrary convex volumes (defined by a set of points), and OBBs (defined by center/extent and forward/up vectors).
This should make it a bit easier to feed Recast with 'solid' data and stop it generating navmesh inside objects, etc.
Arbitrary convex volumes are handled by rasterising all the triangles that compose the volume into a temporary second highfield, and then coalescing all the spans in each cell of that heightfield and merging it back into the main one. OBBs just calculate the vertices and then hand off to the convex volume code.
