Tileindex-raster opacity

[Mark Wright]

I had this issue using USGS maps downloaded from Casil (gis.ca.gov)

I fixed it by putting this into the drg layer:

CLASS
EXPRESSION ([pixel] != 1)
COLOR 0 0 0
END

This worked for 1:100,000 and 1:250,000 scale maps. Had to switch the
expression to != 0 for 1:24,000 scale maps.
