16 Writes z into the given Z-buffer (0 means far away). This function
17 should be used to initialize the Z-buffer before each frame. Actually,
18 low-level routines compare depth of the current pixel with 1/z: for
19 example, if you want to clip polygons farther than 10, you must call
20 clear_zbuffer(zbuf, 0.1).
