The following is a fairly expensive filter but it puts a very nice
blue halo around any object (even objects that have semi-transparent
parts).
<!-- Gives a nice blue halo around any object... -->
<filter id="highlight" filterRes="200">
<!-- Create an object mask -->
<feComponentTransfer result="mask" in="SourceGraphic">
<feFuncA type="linear" slope="10"/>
</feComponentTransfer>
<!-- Soften the mask edges a bit -->
<feGaussianBlur stdDeviation="3" result="mask"/>
<!-- Create a blue halo around mask -->
<feGaussianBlur in="mask" stdDeviation="5"/>
<!-- this colors the halo -->
<feComponentTransfer result="highlight">
<feFuncR type="linear" slope="0" intercept="0"/>
<feFuncG type="linear" slope="0" intercept="0"/>
<feFuncB type="linear" slope="-1" intercept="4"/>
<feFuncA type="linear" slope="1.5" intercept="0"/>
</feComponentTransfer>
<!-- Put the parts togeather -->
<feComposite in="highlight" in2="mask"
operator="out" result="surround"/>
<feComposite in="SourceGraphic" in2="surround" />
</filter>
