Raster Layer, Extent, etc.

[Ian Harding]

I have no idea what I am doing.

I can get mapserver to work as advertised with vector data (geographic
coordinate system) and with raster data (some other crazy coordinate
system) but can't get the twain to meet.  

When I change the extent (as seen in the commented section) one or the
other layers will display, but not both.  I have controls that
successfully turn the layers off and on in isolation, so I know it's not
the DEFAULT versus ON issue.

The system seems to be very forgiving of bad stuff (or absense of any
stuff) in the "projection" section, and the "units" just screws up the
scalebar, but the "extent" seems to be killing me.  

There is only one "extent" section, which applies to the whole mapfile,
right?  From what I have read, the various layers can use different
coordinate systems and be 'translated' to the overall mapfile extent and
coordinate system.  This is not working for me.

What could be causing my pain here?

Thank you in advance....
