Steve,
I think the key part in the question is here:
" and the center point of the symbol is no longer inside the map window".
To my experience a symbol doesn't get drawn at all when the point which
is symbolized is outside the requested extent (WMS mode at least).
To solve that I created the mentioned pull request.
Or do I miss something?

This should already be happening. The drawing code traverses a layer's
class/styles to commute a selection and clipping rectangle that is
larger than the map extent.

Hi Patrick,
i've submitted a pull request for extending the map by a buffer and
then clipping it, so that partial symbols on the edge get rendered as
well (wms non tiled mode).
maybe you can build from sources and use this patch to solve your problem.

Hello Patrick,
if you are using PostGIS as datasource, I would solve the problem by
integrating a st_buffer in the DATA element itself ;) The added bonus
is that you will get the attribute values from a GetFeatureInfo (if
implemented) in the whole buffer zone.
If not, you can try to use tile mode, and add some metabuffer (see
mapserver doc <http://mapserver.org/output/tile_mode.html>)
Cheers!

Hallo,
i have stumbled on a problem.
I am simulating a buffering of point-data with the help of
symbols, which I have set to
sizeunit = meters
size = 760
These rather big symbols disappear from my map when I zoom in and
the center point of the symbol is no longer inside the map window.
But a significant part of the symbol should still be displayed.
Is there any possibility of extending the rendered map, so that
the symbols of my points
are still rendered even when they are outside my map window?
Greetz
Patrick
