.SH DESCRIPTION
.I Gethitcode
returns the global variable 
.B hitcode,
which keeps a cumulative 
record of clipping plane hits.  It does not change the hitcode value in any way.
.PP
The hitcode is a six-bit number, as shown below, with one bit 
for each clipping plane.  (Systems configured without near-far clipping
always return 0's for the near and far clipping planes.)
