I have a quick question regarding filters. I am using the Adobe SVG Plug-in.
I have successfully been working with filters to accomplish drop shadows like
the following:
******************************************
<defs>
<filter id="DropShadow" filterUnits="objectBoundingBox" x="-50%" y="-50%"
width="200%" height="200%">
<feGaussianBlur in="SourceAlpha" stdDeviation="2" result="BlurAlpha"/>
<feOffset in="BlurAlpha" dx="4" dy="4" result="OffsetBlurAlpha"/>
<feMerge><feMergeNode in="OffsetBlurAlpha"/> <feMergeNode
in="SourceGraphic"/></feMerge></filter>
</defs>
**************************************
Now I am trying to accomplish a few typical filter effects like inner
shadow, outer glow and inner glow (like layer effects in Adobe Photoshop for
instance) on an svg feature. I have been through Adobe's tutorial and all
filter effects on their site and others and could not find a sample that does this. I have tryed quickly using the
<feSpecularLighting> and others  without success. Does anyone have samples (or maybe an approach) that
would accomplish these standard effects ?

Thanks in advance !
