[MapServer-dev] More precise WMS GetFeatureInfo for point symbols: ask for opinions

[Steve Lime]

I could also see this enhancement being useful for native point-based
queries too (e.g. mode=query or mode=nquery). If that's feasible, then I
wouldn't tie the configuration to WMS explicitly. What about just using
TOLERANCE AUTO? I mean, it seems that this is trying to address the
limitations of that configuration parameter.
