svgIR uses a mixture of techniques to replace plain text with Scaleable Vector Graphics (SVG). If the script is supported then the heading below will be a fancy font (Agent Orange):
In Opera 8 the image is appended directly as an imported SVG node (because Opera now has native support). The same functionality applies to SVG-enabled mozilla builds, however the replacement element doesn't show up (it's there in the DOM inspector, but you can't see it; I don't know why).
In other browsers, if the
Adobe SVG Viewer
is detected, the image is included using an <object> element.
This works in
Firefox (if you're using
Viewer 6.0 beta), Safari,
Win/IE5-6
and Mac/IE5.
If scripting (or this script) is not supported, the heading will be plain text.
