That was my thought - store in some vector format so all sorts of
resolutions can be accommodated and not worry about shadowing and all
that stuff in the core output format.  Use ImageMagick to do the fancy
fluffy stuff.

It may or may not be desirable to have shadowing in say PDF.  SVG seems
like the easiest candidate to produce that core format and as you said
numerouse editors can output that.

As far as how we produce SVG hadn't thought much about it and not sure
it matters if we use InkScape or whatever.  OpenJump can Save As SVG,
and for me personally that would be my choice since I use it a lot for
ad hoc queries anyway.  I like that I can run my demo query, save as SVG
and be done with it.

For certain cases the raw PostGIS output even using a template would be
a hassle when we need to overlay to show different colors, points etc.
and so forth since it would almost guarantee manual fiddling.

Thanks,
Regina
