28   DESCRIPTION
29       When  the  ray packet size is not known at compile time (e.g.  when Em‐
30       bree returns a ray packet in the RTCFilterFuncN callback function), Em‐
31       bree uses the RTCRayN type for ray packets.  These ray packets can only
32       have sizes of 1, 4, 8, or 16.  No other packet size will be used.
33
34       You can either implement different special code paths for each of these
35       possible  packet  sizes  and cast the ray to the appropriate ray packet
36       type, or implement one general code  path  that  uses  the  RTCRayN_XXX
37       helper functions to access the ray packet components.
38
39       These  helper functions get a pointer to the ray packet (ray argument),
40       the packet size (N argument), and returns a reference  to  a  component
41       (e.g.   x-component of origin) of the the i-th ray of the packet (i ar‐
42       gument).
