Currently a lite version requires libtiff anyway, and since you're distributing binaries it
doesn't seem that bad. Building GDAL from source may be a pain though. (Out of
curiosity does the default build support LZW TIFF or would that require a custom

My vote is for simplification...

I think this makes sense from a maintenance point of view, but I am concerned
that it makes it impossible to built a light version of mapserver with
raster input support.

I am thinking we should move the EPPL7 format into GDAL and then blow away
all format support except for PNG and GIF done using GD (pseudocolored only),
with world files.  Furthermore I think we should only use these drivers if
GDAL is not enabled, and we would need to better clarify the limitations
of the non-GDAL drivers.

In particular, I would like to get rid of the existing TIFF driver which
has some significant flaws, and often gets used instead of GDAL.

I have cc:ed this to the developers list to see if anyone else has an
opinion on the importance of a "light" option for MapServer.
