Changed the raster channels to use a single plane instead of 4 planes. So went from

  12, 1, 1, 0 !ADC ROC#1 Sl#13 Ch#12 Fast Raster X-sync
  13, 2, 1, 1 !ADC ROC#1 Sl#13 Ch#13 Fast Raster X-signal
  14, 3, 1, 2 !ADC ROC#1 Sl#13 Ch#14 Fast Raster Y-sync
  15, 4, 1, 3 !ADC ROC#1 Sl#13 Ch#15 Fast Raster Y-signal
to
  12, 1, 1, 0 !ADC ROC#1 Sl#13 Ch#12 Fast Raster X-sync
  13, 1, 1, 1 !ADC ROC#1 Sl#13 Ch#13 Fast Raster X-signal
  14, 1, 1, 2 !ADC ROC#1 Sl#13 Ch#14 Fast Raster Y-sync
  15, 1, 1, 3 !ADC ROC#1 Sl#13 Ch#15 Fast Raster Y-signal
This works and it makes easier for the mapedit_rasterbcm.pl script to propagate these changes into ENGINE type map files.
