Function: raycastSlab()

function raycastSlab(g, z0, z1, o, d, clip): ExtrusionHit | undefined;

Experimental

Where a ray (in the slab's own world frame) first meets the slab from z0 to z1: its front face (or its plane within NEAR px of it, where the lines along the edge are drawn) or a wall facing the ray, inside the world box clip (x0, y0, x1, y1). The hit point on a wall is moved a hair inside the fill.
