Bill Currie 4a80639556 sw and gl rmisc are now client clean. the graphing functions ahve been pulled
out into r_graph.c (Time and Z graph), cl_ngraph.c (Net graph), and
{gl,sw}_graph.c (R_LineGraph). gl_ngraph.c is gone. Unfortunatly, something
is rather wrong with NetGraph in gl (probably R_LineGraph).
