Minor changes in the comp_beam_engine_hcana.C script.
Set $SWAPRASTERXY to 0 in mapedit_rasterbcm.pl. The raster X and Y are already swapped
in the map files. Setting this to 1 causes the channel assignments to swap thereby causing HCANA to
use the wrong channels for the raster signal types. The signal types are hard-coded in HCANA.
