I think the key part in the question is here:<br>
<p class="MsoNormal"><span lang="EN-US">" and the center point of
the symbol is no longer inside the map window".</span></p>
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).<br>
<br>
To solve that I created the mentioned pull request.<br>
<br>
Or do I miss something?<br>

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

<div>Hi Patrick,</div>
<div><br>
</div>
<div>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).</div>
<div><br>
</div>
<div>maybe you can build from sources and use this patch
to solve your problem.</div>

<div>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.</div>
<div>If not, you can try to use tile mode, and add
some metabuffer (<a moz-do-not-send="true"
