my fault, I'll see if I can change it.
fontsize = atoi(FontSize->answer);
/* figure out space param dynamically from current dispay */
if (R_open_driver() != 0) /* connect to the driver */
G_fatal_error(_("No graphics device selected"));
/* Read in the map region associated with graphics window */
space = fontsize / D_get_u_to_d_xconv(); /* in earth units */
fontsize = 0;
