I have the following code fragment:
ortho(-14.0, 14.0, -14.0, 14.0)
move2(-14.0, -14.0)
....
getgpos(&xw, &yw, &zw, &w)
the result is that xw = yw = w = -1.0, not -14.0 as I expected from
the description of getgpos.
This is inside a library to supplement GL (actually it is the extra routines
from GNU-digs to add hershey fonts etc) so I don't have access to the original
calls to ortho etc.
I have got around the problem by recoding to use relative calls (rmv, rdr
and so on) so that the answer is really for my curiosity...

P.S. I am using a PI withfull graphics and FP options
